Customer Reviews (4.8 / 5 · 5 reviews)

Ruby ★★★★★

I was replacing some bolts on a trailer hitch and these 40mm hex heads seated perfectly with a socket wrench. The 10.9 steel feels tough and the threads caught smoothly right away.

Chloe R. ★★★★★

The partially threaded design made it easy to get them started by hand, and the hex heads took a socket without slipping. A full 150 in the pack gives me plenty for ongoing repairs.

Sophia J. ★★★★★

Used these for a jig fixture I was building and the 10.9 steel held up great under high torque. The hex head seated perfectly with my socket, no stripping. Exactly what I needed for a clean, secure assembly.
