Customer Reviews (4.8 / 5 · 5 reviews)

John ★★★★★

Installed these on a heavy-duty press fixture and the 12.9 strength handled the torque without any deformation. The black oxide finish seems durable so far, no rust after a few days in a humid shop.

Harper ★★★★★

The 220mm length is spot on for my jig setup, and the hex socket drive made torquing them down in tight spots a breeze. Partially threaded means I got a solid grip without fighting the full shank. These are holding up great in my precision assembly so far.

Michael G. ★★★★★

The black oxide finish is a nice touch—it’s even and doesn’t smear when I handle them. Threads cut cleanly into my jig plate, and the 12.9 alloy steel feels seriously tough for the price.
