  • Handy M3 kit
Color: Black M3 Hex Button&Socket Head Kit
These have come in handy for a number of 3D printing projects. And it’s certainly nice to have different length and head options depending on the application. Plenty of each size is given too.

  • Nice assortment.

  • Great quality!
Color: Black M3 Hex Button&Socket Head Kit
Excellent quality. No black soot or greasy mess. Also, they are true oxide. Not just spray painted like most of the screws I have bought on Amazon. It’s a good size collection. They are easy to use and it’s a great value. It’s comes with all the sizes you will need for 3d printer projects

  • Almost perfect for 3D printers
Color: Black M3 Hex Button&Socket Head Kit
Bought this since I have a P2S and printed a lot of stuff. The set is solid with good materials. The box is also nicely designed for ease of use and organization. Yet, there are three things that can be better: 1. no m3*4 and m3*14, not sure why these kits all skipped some common ones and include some really long ones. We have m4m5 for longer tougher jobs. for 3d printing, better coverage of the shorter ones are the key for m3 2. sizes of hex and socket ones are a bit different. I happen to have a L key set so no issue for me, but could cause issues for some folks 3. a lot of the pcs are nuts, maybe as expected in today's world of over advertising ... show more

  • The Abundance of sizes is great!!
Color: Black M3 Hex Button&Socket Head Kit
Came very well and tightly packaged for screws, bolts, etc didn't get mixed into other sizes. Not even necessary but looking out for the customer by providing a wrench in order to utilize the screws and such in this package.
