Customer Reviews (4.4 / 5 · 5 reviews)

Andrew Q. ★★★★★

Used these on a heavy-duty press fixture and the threads were clean and sharp right out of the package. The yellow zinc finish feels tough and should hold up well in a shop environment.

Hannah ★★★★★

Went to torque these down on a jig I’m building and the hex head seated perfectly in my socket—zero stripping even at full force. Yellow zinc finish is already holding up better than the black oxide ones I had before.

Eli ★★★★★

Been using these L9 bolts on heavy equipment repairs and they hold up great under high torque loads. The yellow zinc finish on all 25 pieces was consistent and clean.
