Eli A. ★★★★★

Bought these for a jig I'm building and the 316 stainless is exactly what I needed for the damp environment in my shop. The flat head sits flush perfectly, and the hex socket drives cleanly without stripping. 400 pieces for this price is a solid deal.

Jacob ★★★★★

The hex drive on these M4 screws bites perfectly without any stripping, which is a relief for precise jig work. The 40mm length gave me just enough thread engagement in my assembly jig, and the flat head sits flush as needed. Nice to have a full 400-count box for future projects too.

Samuel F. ★★★★★

I needed a fully threaded 316 stainless screw for a saltwater jig setup, and these M4-0.7 x 40mm cap screws are holding up perfectly so far. The hex socket drive grabbed cleanly with my tool, and the flat head sits flush.
