Customer Reviews (4.6 / 5 · 5 reviews)

Evelyn ★★★★★

I needed some heavy-duty bolts for a press build, and these hex heads turned smoothly with a socket wrench. The 80mm length and class 8.8 rating gave me confidence they’d hold torque, and they’ve been solid under load so far.

Nicholas D. ★★★★★

The partially threaded design made installation quick on my press frame, and the hex head grabbed perfectly with my socket. Zinc plating looks solid and clean out of the package.

Daniel ★★★★★

Finally found some proper M20 bolts locally that aren't junk—these class 8.8s hold my press together without any wobble. The partial threading makes it easy to stack washers on the smooth shank.
