Customer Reviews (5.0 / 5 · 5 reviews)

Owen K. ★★★★★

Needed a bulk supply for ongoing equipment repairs; these fully threaded hex heads are consistent in size and the yellow zinc finish hasn't shown any corrosion yet. Great value for the quantity.

Mia ★★★★★

Used these to replace worn bolts on a press brake at work, and the Grade 5 steel held up way better than the old ones. The hex heads fit my socket perfectly without stripping.

Joshua E. ★★★★★

Installed these on a conveyor guard today and every single one threaded in without any binding. The zinc coating has a consistent, slightly glossy finish that should hold up well in a dry shop environment.
