Customer Reviews (4.4 / 5 · 5 reviews)

Ruby M. ★★★★★

The hex head on these M20 screws gave my socket wrench a really solid grip, and the 280mm length was just right for bolting down a heavy machine base.

David A. ★★★★★

Installed these on a conveyor belt support frame and the hex heads grabbed perfectly with a socket wrench. The 8.8 steel feels plenty sturdy for industrial use.

Benjamin P. ★★★★★

I needed some heavy-duty bolts for a press jig, and these M20 cap screws have the grip length I was after with their partial threading. The hex head made tightening with a socket wrench effortless, and the 8.8 steel feels solid.
