Customer Reviews (4.6 / 5 · 5 reviews)

Christopher ★★★★★

These bolts fit perfectly into my tractor's loader mount, and the Grade L9 alloy steel feels seriously tough. The yellow zinc coating was a nice bonus for rust resistance, and the hex head made torquing them down with a socket quick.

Sofia E. ★★★★★

Went on without a fight, even in the tight spot I was working in—the Grade L9 steel feels seriously tough and the zinc coating gives it a nice, uniform finish. Fastened a heavy jig plate with all 16 and none of them so much as stripped a thread.

Owen G. ★★★★★

The hex head on these bolts gives my socket a solid grip, and the yellow zinc coating seems durable. They threaded smoothly into some heavy equipment brackets without any binding.
