Customer Reviews (4.8 / 5 · 5 reviews)

Daniel ★★★★★

The partial threading on these M42 bolts made aligning them in the machinery mount much easier than with fully threaded ones. They tightened down firmly with a socket wrench and feel like they can handle serious torque.

Lucy V. ★★★★★

The partially threaded section grabbed perfectly when I torqued it down on the equipment frame, and the hex head took a socket wrench without any slipping. For a bolt this size, the class 10.9 steel feels rigid and dependable. Exactly what I needed for a solid industrial fit.

Isabella W. ★★★★★

Used these for mounting a heavy motor base plate — the 380mm length was exactly what I needed to reach through the frame. The Class 10.9 steel feels solid enough for the torque specs I was targeting.
