  • Great value
    High quality
  • Great Product – Exactly What I Needed!
    I was a little skeptical at first, but this item turned out to be exactly what I was looking for. It arrived on time and in good condition. The quality is solid, and it works just as described. Setup was straightforward, and I’ve had no issues so far. Definitely worth the price. I would recommend this to anyone considering it!

  • Worked for Almost Everything That Moved
    These WD40 works on everything I used them for that moves. My windows were a bit difficult to slide open and once I sprayed the metal parts, the windows open and close with ease. I had a new metal part added to the car, so to protect them from rust, I sprayed it with WD40 because my understanding is that not only does this liquid prevents friction in moving parts, but they prevent rust buildup. I sprayed my parents screen door and it slides quickly now. I sprayed it on my car windows, and they now slide open and close much faster now, except it was a hassle to clean the glass until I used Windex on it. Only thing that didn’t seem to work as well on was my paper shredder that was getting stuck. I thought spraying it would get the cutting metals to work better, but instead the papers were shredding much slower and the shredder actually over heated momentarily. Overall though, this WD40 comes in handy for many uses. I heard it can even defog car lights.
  • Great product for home projects that involve machinery
    Great product for working on projects around your home especially vehicles and machinery parts

What Customers Say:

  • Kroil is “GOOD STUFF” best penetrant by far
    Best penetrating oil on the market by far! I’ve been using it since the 1960s when it was only available to industry. I’m glad it’s readily available to all of us today. It really does lossen frozen fasteners in cars, boat engines, motorcycles, farm equipment, ect. I also works as a firearms bore cleaner when mixed into bore cleaning solvents (25% Kroil/75% Bore solvent.) The Kroil “creeps under metal fouling in the barrel rifling loosing it for easy removal. Kroil is just “Good Stuff”
  • It’s magic
    This stuff works. Gets under corrosion and breaks its’ bond within the joint. Good for treating valve stems. Mineral deposits sluff off because they can’t stick anymore.
  • works OUTSTANDING for me!!
    when all else fails, this stuff is a legend. had a reloading die set that had not seen action for about 10 years,the seater die was seized up, i tried cleaner, oil and as much brute force as i dared with a crescent wrench,no go, so i got a can of liquid kroil and poured a generous amount into die, let it sit while the box endwrench set and vice grips were shipped. once all that came together all is well.
  • Worth every penny!
    Kroil is, hands-down, the most effective penetrating oil I have ever used. I was trying to drive rusted pins from a cylinder and they would not budge, even after liberal application of PB Blaster. I tried a few drops of Kroil, waited 10 minutes, then added just a little more and the pins started moving! It’s amazing stuff and just a dab’ll do ya!
  • It works quickly and you don’t have to wait long to see the results.
    I’ve been using Kroil Original Penetrating Oil for a while now, and I can honestly say it’s one of the best penetrating oils I’ve ever used! Whether I’m working on rusted bolts, stuck machinery parts, or even old tools that have been sitting unused for years, this product gets the job done quickly and efficiently.The penetration power of Kroil is unmatched. It seeps into the tiniest cracks and breaks down even the toughest rust and corrosion. In many cases, I’ve been able to loosen parts that I thought were impossible to get unstuck, saving me time and frustration. It works fast, and you don’t have to wait long before you see results.The application is easy, and the spray nozzle gives a controlled, fine mist that ensures the oil gets into the tightest spots without waste. I appreciate how it doesn’t leave a greasy residue after use, making cleanup a breeze.
  • works good
    great
  • Best penetrating oil out there.
    As someone who restores vintage shotguns and rifles, Kroil is an indispensable part of my toolkit. Stubborn, rust-locked screws and pins loosen up and come out fairly readily with the proper application of Kroil and some elbow grease.It’s not a lubricant for long-term use, but a penetrating oil made to get things moving when they’re stuck tight. It’s not WD-40 (which is actually a water-displacement chemical, not a lubricant) that you can spray on just about anything for a quick bit of slip-and-slide, but rather a tool for stubborn parts that don’t want to budge when they should move freely. One small 8-oz can will last you a very long time with proper application.Kroil is certainly odiferous, but it’s not a bad smell, just unique. As sportsmen of the world can attest, Hoppes #9 is similar in the sense that you know what it is by smell far faster than by looking at the label.At $18+ for an 8-oz can, it’s not exactly cheap on Amazon, but I assume part of that is the cost of shipping something that could ostensibly be considered hazardous. When it comes to getting something unstuck, you’re generally willing to pay just about anything, so it’s not terrible, especially with how long a can will last you.
  • Primes up old stubborn parts with deep penetration
    Kroil has always been the best oil lube for getting into tight or rusty spots.Not compatible with latex or flesh.

What Customers Say:

  • Very impressed with the quality!
    I bought 6 sets of these in different lengths and am highly impressed. Sturdy, precisely formed, cleanly cut, individually wrapped in protective plastic, then boxed. They all arrived in excellent condition, no dings, dents or bends. There were a few minor burrs on the ends from the cutoff saw, but they were so minor 1 or 2 strokes of a fine file removed them. Honestly, if I didn’t have a file I could have left them as is–VERY nice!
  • Nice product.
    Perfect. Used for custom camper cabinetry, a kids light table, straight edge for cutting. Versatile and high quality.
  • great for projects
    I recently purchased 10pcs 48inch T Slot 2020 Aluminum Extrusion European Standard Anodized Linear Rail, and I was able to get an open box set for a great price. The value for this product is excellent, especially if you are collecting extrusions for a build one day.The aluminum extrusions are well-made and durable, with a smooth and consistent anodized finish. They are also very versatile, as they can be used for a variety of projects and applications, from building furniture to creating custom 3D printers.Despite being open box, the extrusions I received were in excellent condition, and they were packaged securely to prevent any damage during shipping.Overall, I would highly recommend 10pcs 48inch T Slot 2020 Aluminum Extrusion European Standard Anodized Linear Rail to anyone looking for a high-quality and versatile building material. The value is excellent, especially if you can find an open box set for a discount.
  • worked perfectly and exact size
    These were exactly cut for my project and doesn’t scratch with durable anodized (not painted, i have gotten some that was painted) My 3d printed T-Bolts worked great also.
  • Poor Anodizing but great value
    The price is great, but the anodizing is weak. Look at it wrong, and it scratches. Other than that, it’s a great value for the money.
  • Support Structure Applications
    Excellent material to work with. It’s great for structural support projects!
  • Works great on sim rigs
    Good product, works as advertised.
  • The product is so flexible.
    The extrusion helps in proof of concept design / builds, is so flexible can be made into anything… multiples of power amplifiers… I would not, cannot imagine approaching my ideas with any other product.

What Customers Say:

  • Great bearings good price.
    Item as described. Really well made. One was a little tighter then the other and did not rotate as freely but for my application it was fine. It does have grease fitting so it can stay lubricated after many hours of use. Operated smoothly and with out issue or defect. Bolt location was uniform and easily mounted to my structure.
  • Great value and works like they should
    These worked perfectly for the auger jackshaft system I built for my bin. They’re super easy to use since they self align, run smoothly, and seem like great quality. Great value for the money and I wouldn’t hesitate to buy them again.
  • Impressive
    I picked these up to use for my steering on my Baja Bug build. When I was looking at the measurements in th head I was a bit worried they would be too big to use. As it turns out they are perfect and WAY better than what you find on the off road websites. These are not flimsy and cheap. They are robust and built very well and will most likely out live the Baja. I am very impressed with them, the fact that they have zert fitting’s is fantastic as I can lube them up after playing out in the desert. The price is amazing as these are well worth more.
  • Parece fuerte
    Al parecer se ven buenas y fuertes, una observación el paquete llegó abierto y le faltó una tuerca pequeña de las que van en el rodamiento
  • Awesome product
    Great product worked perfect for my project
  • If you are looking for a cheap Bearing this is for you with Great Quality!
    I purchased this for a project I am building (retractable golf simulator screen mechanism), and cannot be more happy with the product! It has all the features listed and they are all working as should be. I am amazed at how heavy duty this product is. While cleaning up a CR 3/4 Bar stock to fit in the bore of this, I dropped the same product a dozen time or more on concrete from a height of 4′ and not cracks or breaks, Paint is very minorly chipped.I would recommend.
  • Solid and fits a 3/4” shaft with no play
    Solid built. Fits snug on 3/4” shaft with no play.
  • Good pillow blocks, good price.
    Great pillow blocks for the price. I added a set of wheels to my table saw to move it around easier and these worked like a charm.

What Customers Say:

  • Quality magnet wire – perfect for building baluns
    This BNTECHGO 18 AWG magnet wire is excellent quality and worked perfectly for building a balun for my antenna system. The enameled copper wire is consistently gauged throughout with a smooth, even coating. No thin spots or inconsistencies that would cause issues.The enamel insulation is durable and holds up well to winding around cores without flaking or cracking. The wire is flexible enough to work with easily but maintains its shape once wound. Stripping the enamel when making connections is straightforward with a lighter or scraping.The 18 AWG size is perfect for common balun builds—thick enough to handle power but not so heavy that it’s difficult to wind tightly. The copper quality is evident in the wire’s consistency and the clean solder connections it makes.For the amount of wire you get, the price is very reasonable. Having a good supply on hand means I can experiment with different balun designs without worrying about running out. The spool keeps everything organized and tangle-free.Whether you’re building baluns, transformers, inductors, or other RF components, this is quality magnet wire that performs exactly as it should.Highly recommend for any ham radio or electronics projects!
  • Great For Hand Made Coils
    If you make your own coils this is great wireI am an experimenter and frequently change coil configurations and reuse wire if availableVery happy!
  • Easy to keep on hand
    I needed this for a science experiment for my son’s fourth grade home school class. It worked very well. It’s nice that it comes in a spool, as some wire I’ve ordered through other people has not always been on a spool.The only downside is that it has the insulation coating, which is the red you see on the outside of the wire. You have to scrape off that coating to make the wire show on the ends to be able to have conductivity. This is difficult to do efficiently on such thin wire, and often end up with little stripe at the tips that aren’t fully scraped off and block the current from flowing through the wires. Also, it creates tiny metal shavings which you then have to ensure all end up in the trash so the cats don’t lick them up or the children don’t get them in their eyes. If none of these concerns pertain to you, then this is the perfect product for you. Me personally, I would prefer next time to purchase something with a wire coating instead.I would recommend this to others, I would just also make sure they know about the shavings because it’s for each of us to decide if we’re ok with it or not, or just to know to watch for it.
  • Great mag wire, but….
    I bought the 32 AWG Magnet Wire 4 oz spool. I am an electrical design engineer, so I use quite a lot of this. Great wire, enamel scratches off nicely, solders nicely, not prone to breaking, BUT when I reached for this 4oz spool in my parts kit, one end of the spool had broken off, and I suddenly had this bird’s nest pile of 32 gauge wire–yuck!It looked to me like they crammed too much wire on the the spool. I chucked it and reordered the 2oz spool. I highly recommend this wire, but buy the 2oz spool.
  • Quality copper wire!
    Good quality copper wire for constructing ham end fed antennas! You have to scrape or sand off the enamel on areas to make clean solid solder points, but that is the process with most protected copper wire. Great stuff!
  • Love the finish, quality roll
    Great for fixing broken tracks on circuit boards!
  • Multi purpose wire
    This stuff is fantastic! I recently used it to modify a Super Nintendo Junior console for RGB output. The great thing about magnet wire in my book is the firmness of it. It might not be entirely intended for the case I was using it for but it makes running wires around circuit boards so much easier as you can bend and shape it to a precise path without having to tape it down to keep it in place. The insolation seems fairly good too as the signal interference that I was getting using my previous wire is no longer visible when running the SNES thru a video upscaler.Great stuff and it’s going to be my “go to” wire from now on.
  • Good for wiring
    Good for rework PCB. The insulator can be melted by soldering iron+flux. No need to stripe it out.

What Customers Say:

  • Great quality, work great for exercise.
    Great value for the money, the smoothness, size, weight, and bearing quality are excellent. I got these to use for hand exercises, and they are working great. They’re exactly like the solid baoding chinese exercise balls, and this package has enough to use with both hands at the same time. They are even large enough to do the burn through science trick smacking them together with a piece of paper between them.
  • Love the bearing, hate that Amazon shipped it in a paper bag
    Amazon package this very heavy item in a paper bag along with a delicate electronic item. I’m surprised that the bearing did not bust out of the bag before it got to me. I don’t know who thought this was a good idea. The box the bearing was in was also beat up but luckily the bearing survived in good shape. Not the seller’s fault this was shipped by Amazon. Love the bearing, will make a nice addition to my weird metals collection.
  • Heavy, Useful Steel Balls With Many Applications
    I bought these 1.5″ (38mm) steel balls to clear clogs in my shop vac hose. Every week I vacuum a chicken coop with wood shavings, and waste clumps sometimes block the hose. These balls are the perfect size and heavy enough to roll through the hose and break up the clog.Even if you don’t have chickens, you might still enjoy them. They’re solid, satisfying to hold, and could be useful for many projects. The finish is polished steel (not chrome), so they may rust over time, but they can be kept in good shape with a little care.
  • Seems good,
    Smaller than I realized, but round and shiny, makes good bug eyes,
  • Fun to play with
    Great for projects
  • Watch ordering your size
    A little bit big for intended use (sling shot ammo) but quality manufactured product. No spree perfectly round.
  • No complaints
    Heavy, and heavy duty
  • If someone says you need to “get some balls”, these work well.
    Exactly what I ordered.

What Customers Say:

  • Impressive steel ball!
    This thing is massive; it weighs almost 20 pounds and is a conversation starter. I have this sitting in front of my desk and everyone who comes by tries to pick it up. Most can’t, but it’s fun to watch them try. Solid polished steel, not chrome plated, it really is amazing, even just to look at!
  • Perfect For a Display
    These bearings are perfect for my display. I am sure they would be great for their intended use, but I am using them as decorations in a display. These precision cut bearings work well and they add that little extra exactly where it is needed. All 5 bearings are in great condition. The size and shine are exactly what I hoped for when I bought them. The bearing size is very good as is their weight. They are very durable, too. Recommended… in displays and in their original, intended use.
  • Perfect, heavy, mirror sphere!
    Well heck! I didn’t think it was going to be so perfect. I bought it as a sail shade weight to anchor against wind. The surface of this monster looks like a perfect mirror, a proper gazing ball, if you will. I’m reluctant to drill it and let it get scratched up. I guess I’ll have to mess around with it until I naturally bruise it up. It is HEAVY, a seriously dense, polished, perfectly round sphere. I showed it to my neighbor and handed it to him -he almost dropped it because the heft is so unexpected. package arrived quickly, and I’m both pleased and humbled.
  • Great quality.
    Great for testing anvils!
  • steel ball bearings
    nice product
  • Good for hand exercises
    I use this for a good hand and wrist workout. Perhaps not its intended use, but that’s alright by me.Good size to grip in the hand while remaining maneuverable. I made sure to clean off the packing grease before trying to grip it (don’t want this to slip out and fall on my foot). So far it’s still remained rust free, despite openly sitting on my desk between uses. Pretty shiny – enough to act like a distorted mirror – though I could give it a good polish if I want to take my handprints off it.Since I’m not sticking it in a machine, I can’t speak to its concentricity or any other important factor. Feels pretty round, though.
  • Made a tool for working copper.
    I am a hobby blacksmith and I purchased this ball bearing to create a tool for shaping and texturing copper ladles.I have made several copper as well as steel ladles on this bearing now. I’ve missed a couple times with my hammer but the bearing still has no mars or dents. Very tough smooth steel! It has also been out in my barn for months and there is absolutely no rust. This tool should last a LOOONG time.I was actually surprised at the affordability of this item, I had thought a bearing this big would cost a lot more. Very happy with my purchase.
