Sophia V. ★★★★★

I needed a bulk pack for my 3D printer's linear rail mounts, and these M4 screws fit perfectly with consistent threads across all 400 pieces. The zinc plating gives them a nice, even finish that resists rust in my tool drawer.

Abigail ★★★★★

Just finished a small jig build and these M4s held everything square with zero stripped sockets. Threads cut clean and the zinc plating looks consistent across all 400 pieces.

Michael P. ★★★★★

The hex drive cut perfectly on these, no stripping even after multiple tightenings. I'm using them for jig assembly, and the zinc coating gives a nice, consistent finish across all 400 screws.
