Joshua G. ★★★★★

The yellow zinc coating is flawless and the threads are sharp, so they grab right away without any galling. I used them to bolt down a heavy conveyor frame and the L9 grade steel gives me zero worry about shearing under load.

Violet ★★★★★

These bolts threaded cleanly into an old piece of farm equipment where I’d stripped the holes before. The L9 alloy feels noticeably tougher than the grade 5s I’ve been using, and the yellow zinc coating should hold up well against a little moisture.

Owen ★★★★★

I finally replaced the aging fasteners on my press with these and the hex heads held up great under torque. The threads are clean and the yellow zinc coating looks like it will resist rust well.
