Lily M. ★★★★★

The zinc plating looks clean and uniform across all 25 pieces, and the fully threaded shaft made alignment with my equipment frame a breeze. Hex head grabbed the socket snugly with no stripping, and at class 8.8 they feel properly beefy for the torque I put on them.

Avery ★★★★★

Needed these for a heavy-duty frame repair and the hex head fit my socket perfectly without any wobble. The zinc plating looks even better than standard black oxide, and all 25 threads were clean with no burrs.

Timothy Y. ★★★★★

I was a little worried about thread quality on a bulk pack, but these M18s drove clean and seated flush every time. The zinc plating has a consistent finish and the hex heads haven't rounded off under an impact wrench. Solid value for the price on our assembly line.
