Matthew X. ★★★★★

The yellow zinc finish on these looks great and seems like it’ll hold up on our equipment. Threads were clean and the heads seated perfectly with a socket wrench, no issues at all across all sixty pieces.

Eli ★★★★★

These replaced some worn bolts on a large press, and the hex head made it easy to get full torque with a socket. The yellow zinc coating looks solid and should resist rust well. Fast shipping and exactly the grade 8 strength I needed.

Jacob J. ★★★★★

I needed a long bolt for a heavy machinery baseplate, and these 6-3/4" Grade 8 cap screws threaded in with zero wobble. The yellow zinc coating looks durable too.
