Customer Reviews (4.8 / 5 · 5 reviews)

Ava ★★★★★

I needed high-strength screws for a heavy tooling fixture, and the Class 12.9 hardened alloy steel on these is exactly what I was hoping for. The black oxide finish also held up well during assembly without any galling.

Sophia A. ★★★★★

Installed these in a jig for a production run, and the 12.9 alloy steel held up perfectly under heavy loads without any deformation. The partially threaded design gave me exactly the clamping length I needed for the assembly.

Kevin ★★★★★

The hex drive on these M20 screws grabbed the wrench perfectly without slipping, and the black oxide finish feels tough enough for my jig setup. They’re exactly the length I needed for a heavy-duty assembly, and the partial threading made alignment much easier than fully threaded bolts.
