Customer Reviews (4.8 / 5 · 5 reviews)

Edward ★★★★★

I was relieved these were actually fully threaded, which made a difference for fitting through a tight assembly bracket. The hex heads grabbed my socket cleanly without any slipping, and they threaded smoothly into the tapped holes.

Hannah U. ★★★★★

Finally a batch of M10 bolts that are actually consistently Class 10.9 hardness—these didn't strip when torquing down the motor mounts. The fully threaded design gave me plenty of grip length for a solid connection.

Michael ★★★★★

Used these to bolt down a heavy-duty press at the shop—the class 10.9 steel held up perfectly under constant torque without stripping. The fully threaded length gave me plenty of grip even with stacked washers. Exactly what I needed for a reliable industrial fix.
