Customer Reviews (4.6 / 5 · 5 reviews)

Benjamin H. ★★★★★

These bolts threaded perfectly into the existing mounting holes on my press with no binding at all. The L9 alloy feels noticeably tougher than the old hardware I was replacing.

Richard ★★★★★

Installed these on some heavy equipment guards and the hex head took a socket perfectly without slipping. The yellow zinc coating looked consistent across all 20 bolts.

Carter ★★★★★

The threads on these are cut clean and the yellow zinc finish is consistent across all twenty bolts. They torqued down smoothly on our equipment frame without any binding, and the partially threaded section gives us that solid grip we needed.
