Brian ★★★★★

Needed some high-strength fasteners for a custom tooling fixture, and these Class 12.9 alloy steel screws handled the torque perfectly. The hex socket drive engaged my wrench without any slipping, and the zinc plating has a clean, even finish.

Sophia L. ★★★★★

The threading on these M12 cap screws is perfectly clean, and the 12.9 alloy steel feels seriously tough straight out of the package. I used a full dozen for a jig build and every single one seated without any binding.

Ryan P. ★★★★☆

The hex socket drive on these worked great with my torque wrench, and the zinc plating looks clean and durable. Only minor thing is the 55mm length was a hair shorter than I hoped for my jig setup, but the threads are perfectly cut. Solid buy for precision work.
