Customer Reviews (4.8 / 5 · 5 reviews)

Grace B. ★★★★★

The yellow zinc coating on these Grade 8 bolts is consistently applied across all 100 pieces, with clean threading that allowed my socket to spin on smoothly. Fast shipping and perfectly sized for the machinery mount I needed.

Leo ★★★★★

The yellow zinc finish on these Grade 8 screws held up perfectly when I used them to mount a guard on my milling machine, and the partial threading made alignment much easier.

Thomas ★★★★★

Installed these on a heavy equipment guard and the Grade 8 steel felt rock solid under torque. The hex head drove smoothly with a socket and the yellow zinc finish looks clean.
