Customer Reviews (4.6 / 5 · 5 reviews)

Isabella ★★★★★

The hex drive seated perfectly on my wrench, and the partial threading grabbed cleanly in a steel jig I’m building. Class 10.9 strength feels solid, and the black oxide coating looks even better in person.

Adam ★★★★★

I was a bit skeptical about the black oxide finish holding up, but after tightening these into a steel jig frame they look and feel really durable. The hex socket drive made it easy to get a solid grip with my driver, even in a tight spot.

Sebastian Q. ★★★★★

The partial threading on these M20 screws was perfect for my machinery setup, giving a tight grip without needing full-length threads. The black oxide finish also feels robust and hasn't shown any wear after a few installs.
