Eli ★★★★★

I've been using these for jig fixtures, and the flat head sits flush perfectly. The 18/8 stainless is holding up great in a slightly damp shop environment without any rust.

Aurora ★★★★★

Needed some longer partially threaded M4s for a custom jig project, and these 40mm ones have the perfect grip length with a clean hex drive. The 18/8 stainless feels solid and corrosion-resistant for the shop environment.

Nicholas G. ★★★★★

I was pleasantly surprised by how precise the threading is on these M4 screws—they seated perfectly in my jig without any wobble. The 40mm length is just right for the mounting brackets I'm assembling.
