Customer Reviews (4.8 / 5 · 5 reviews)

Ruby S. ★★★★★

The hex head design made it easy to grip with a socket wrench during a tight assembly, and the zinc plating held up well against minor scratches. Threads ran clean through a steel bracket without any binding.

Henry O. ★★★★★

Took these to the workbench and the zinc coating is consistent across all 400 pieces, and the hex drive grabs cleanly without stripping even on the tightest M3 spots. Threads cut smooth into steel brackets right out of the bag.

Robert U. ★★★★★

Pulled one out of the bag and measured it against a cheap bolt I had lying around—the threading is noticeably crisper, and the zinc plating looks like it'll hold up well. For 400 pieces at this price, the consistency is honestly the best part.
