Customer Reviews (4.6 / 5 · 5 reviews)

Matthew ★★★★★

I needed M20 bolts for a heavy machinery bracket and these class 8.8 hex heads fit perfectly with my socket wrench. The zinc plating looks clean and should hold up well in my garage environment.

Julian ★★★★★

The partially threaded design made all the difference—I could seat them fully against the flange without fighting the threads. The zinc plating looks even and clean out of the pack, and the hex heads grabbed my socket wrench without any slip.

Aurora ★★★★★

These M20 bolts fit perfectly into my press jig, and the partial threading gave me just the grip length I needed without any wasted shank. The 300mm length was spot-on for my application.
