Elizabeth U. ★★★★★

Having replaced cheap screws that stripped out constantly, these went in cleanly with no issues. The 18/8 stainless steel feels solid, and the hex drive makes them easy to tighten without slipping. Glad I bought the bulk pack of 600 for future projects.

Owen L. ★★★★★

I was a bit skeptical about getting 600 screws at this price point, but these M4 x 12mm socket caps are surprisingly consistent—no stripped threads or burrs. The 18/8 stainless finish has a clean, uniform look that works perfectly for my jig builds.

Violet ★★★★★

Used a batch to fasten a custom machinery guard down and every single screw threaded in clean without any wobble. The 18/8 stainless steel finish is much more uniform than the mixed-grade packs I’ve bought before.
