Leo Q. ★★★★★

The zinc coating on these grade 8 bolts looks clean and uniform, and the hex heads grabbed my socket without any stripping. I used them to re-secure a heavy conveyor frame and they haven't budged after a week of vibration.

Leo G. ★★★★★

The partial threads seated perfectly against the flange on my press brake repair, and the hex heads didn't strip under a 250 ft-lb impact wrench. Zinc plating looks uniform across all 200 pieces, which is a relief for a bulk order.

Elizabeth ★★★★★

Installed these on a heavy-duty jig in my shop and the Grade 8 rating gave me confidence they'd hold up. The zinc plating looks clean and the hex heads seated nicely under my socket wrench.
