Emma I. ★★★★★

Torqued these down on a jig frame this morning and the hex head seated cleanly with a 19mm socket. Threads ran smooth the whole way, and at 55mm fully threaded they gave me just the grip I needed for a double-nut lock setup.

John O. ★★★★★

The zinc plating on these M12 bolts is evenly applied with no rough spots, so they thread into tapped holes smoothly without binding. I used them for mounting a heavy steel bracket and the class 8.8 strength handled the torque without any flex. One hundred fasteners for this price is a solid deal fo

Victoria ★★★★★

I was pleasantly surprised by how well the zinc plating held up during a heavy machinery assembly job. These fully threaded screws made it easy to get a tight fit, even in awkward spots, and they didn’t strip under torque.
