Customer Reviews (5.0 / 5 · 5 reviews)

Olivia ★★★★★

These bolts threaded perfectly through some heavy equipment mounting brackets I was repairing. The Grade 8 steel feels incredibly tough, and the hex head gave my socket wrench a solid, slip-free grip.

Miles ★★★★★

I needed some heavy-duty bolts for a piece of farm equipment, and these 9-inch Grade 8s threaded in smoothly without any binding. The hex heads gave my socket a solid grip, and the yellow zinc coating looks tough enough to handle the elements.

Elizabeth D. ★★★★★

The yellow zinc coating is flawless across all 45 bolts, and the hex heads grip perfectly with a socket wrench. Threads are clean and uniform, exactly what you want for heavy machinery work.
