Customer Reviews (4.6 / 5 · 5 reviews)

Timothy B. ★★★★★

Installed these on a heavy-duty press fixture and the Grade L9 strength held up perfectly under high torque. The yellow zinc finish still looks clean after a few weeks of shop use.

Robert K. ★★★★★

These bolts fit perfectly into my tractor's lift arm bracket, no burs on the threads at all. The L9 alloy steel feels much tougher than the standard hardware store stuff I've been using.

Miles ★★★★★

The threads were clean and the yellow zinc finish looks solid, a good match for the rest of the hardware on my press. These are holding torque well after a week of heavy use, so the L9 alloy was worth the cost.
