Customer Reviews (4.6 / 5 · 5 reviews)

Matthew P. ★★★★★

The hex socket drive bit snugged right in without any wobble, and the black oxide finish looks clean against my jig setup. These 12.9 alloy screws feel solid for the heavy clamping I'm doing—should hold up well over time.

Ella ★★★★★

I was a little unsure about the size at 280mm, but the 12.9 alloy steel feels incredibly rigid and the threads are cut cleanly, no binding at all when I torqued them into my fixture. The black oxide finish is even and should hold up well in the shop, and the hex socket seated the driver perfectly.

Eli H. ★★★★★

The black oxide finish on these M22 screws held up perfectly during my tooling setup, no chipping at all. The hex socket drive made installation straightforward with my torque wrench, and the 280mm length was just right for my precision assembly.
