Customer Reviews (4.6 / 5 · 5 reviews)

Brian I. ★★★★★

I needed a fastener that could handle serious torque for a custom press fixture, and the 200mm length plus the Class 12.9 rating made these exactly what I was after. The hex socket drive engaged cleanly with my Allen key, and the black oxide finish has a nice low-glare look.

Lily ★★★★★

Installed these in a heavy-duty jig and the hex socket drive held up perfectly under full torque. Class 12.9 strength feels solid—no stripping or deformation during assembly.

Richard T. ★★★★★

The thermal black oxide finish on these screws looks professional and seems to resist wear well in my jig setup. The 200mm length was exactly what I needed for a deep assembly, and the threading pattern held securely without slipping.
