Customer Reviews (4.8 / 5 · 5 reviews)

Avery T. ★★★★★

Installing these on a jig I’m building, and the hex socket drive made it so much easier to get a firm grip without stripping. The 18/8 stainless steel feels solid and won’t rust.

Madison ★★★★★

I needed 30mm fasteners for a tight assembly jig, and these M4 screws fit the bill perfectly—the hex socket drive held steady without stripping during installation. The 18/8 stainless steel feels solid, and having 600 in one pack means I won’t run out mid-project.

Sebastian B. ★★★★★

Finally, a pack of 600 that actually comes with consistent threading—every single one of these M4 screws threaded smoothly into my aluminum tooling jig. The flat head sits flush without any wobble, and the 18/8 stainless feels solid enough for repeated adjustments.
