Julian M. ★★★★★

I’ve been using these M12 bolts for mounting a jig on my press, and the fully threaded design gave me the grip I needed. The class 10.9 steel feels much sturdier than the hardware store stuff I used before.

Ruby B. ★★★★★

I needed a bulk pack of M12-1.25 bolts for a frame repair, and these 40mm fully threaded screws fit perfectly in the socket. The class 10.9 steel feels sturdy and the hex head gripped well with my socket wrench.

Stella S. ★★★★★

The hex heads are machined perfectly; my 13mm socket grabs them without any slop. I used about half the box on a heavy equipment frame, and not a single one stripped during torquing. Will definitely reorder when I run out.
