Customer Reviews (4.6 / 5 · 5 reviews)

Carter ★★★★★

These bolts fit perfectly in my industrial jig where I needed a strong, partial thread for clamping. The hex heads grabbed cleanly with a socket wrench and the 8.8 steel feels plenty tough for the job.

Samuel Q. ★★★★★

I needed a batch of partially threaded bolts for a machinery repair, and these 40mm M12s worked perfectly. The Class 8.8 steel feels solid, and the hex head seated nicely with my socket.

Jacob C. ★★★★★

The hex head on these M12 bolts fits my socket perfectly, making installation on a jig frame quick without stripping. The 8.8 steel has held up well under moderate load without any visible deformation. A solid choice for general industrial fastening.
