Customer Reviews (5.0 / 5 · 5 reviews)

Chloe ★★★★★

The yellow zinc finish on these bolts looks great and held up perfectly when I used them to secure a heavy-duty press. Each one threaded cleanly into my tapped holes without any binding.

Isabella ★★★★★

Threaded them into a piece of heavy equipment and they seated cleanly without any binding. The L9 steel feels solid, and the yellow zinc held up fine against a bit of shop grime.

Claire ★★★★★

The yellow zinc finish on these Grade L9 bolts looks flawless out of the package, and the fully threaded shaft made cinching down a stubborn machine guard a breeze. Each of the fifty heads seated cleanly with a socket wrench, no stripped edges or burrs to fight.
