Jacob M. ★★★★★

Threaded these into an existing mount on my press and the Grade 8 steel held torque perfectly without stripping. The yellow zinc coating looks factory-fresh too, which is a nice bonus for outdoor use.

Andrew ★★★★★

Needed these for a heavy equipment jig I'm welding up, and they torqued down without any binding. The yellow zinc finish is even and the threads are cut clean. Solid set of fasteners for the price.

Carter U. ★★★★★

The packaging held 25 clean, well-formed bolts with crisp threads right out of the box. I torqued a few down on a heavy jig frame and the yellow zinc finish didn't even scuff, which beats the last batch I got from another supplier.
