  • 4mm isnt that small right?
Size: M3 x 4mm
I don’t usually have strong opinions about screws, but these M3 x 4mm little guys earned a review. M3 isn’t that small, but somehow the second you drop one, it becomes invisible. I’m convinced they hit the floor and immediately enter stealth mode. Honestly, they should come in neon colors so you have at least a fighting chance of finding them again. That said, they do exactly what you want. Threads are clean, fit is consistent, and they go in without any drama. No stripping, no fighting alignment, just solid, reliable hardware. No complaints on performance, just keep a magnet handy… or a flashlight… or maybe just buy extras. ... show more

  • Great quality
Size: M6 x 12mm
Great quality, excellent price. Used with LabRax 10" server rack 3d print project. Would buy again. Comes with simple allen key as well.

  • High quality bolts
Size: M5 x 10mm
These bolts are super nice and premium quality. Very strong and accurate manufacturing tolerances. Worked great with aluminum 2020 extrusion constructions. Comes clean without any grease/oil in a nice little plastic case. Would buy more from this brand specifically in the future.

  • They are what they said they are.
Size: M6 x 10mm
Screws are great, case locking mechanism on the case is also solid unlike many smaller screw size cases. Used them to make a Lab Rax 15u home lab rack.

  • Very happy with these screws
Size: M4 x 8mm
Look and work exactly as expected. Appreciate that it came in a nice box with an allen wrench. Additionally, the finish is even which isn't always a given at this price point.

  • Value and good quality
Size: M3 x 12mm
They are screws, they are the right size, the package count was accurate, work as expected. What else could someone say. A budget friendly option.

  • High Quality Fasteners
Size: M2.5 x 10mm
These machine screws were perfect. Very high quality, nicely formed threads and consistent size. Better quality than some of the other hardware I’ve bought on Amazon and locally. Highly recommended.

  • Excellent long screws
Size: M4 x 65mm
Great quality. Straight and nice, full length threads. Hard to find such long screws.
