Customer Reviews (4.8 / 5 · 5 reviews)

Ruby ★★★★★

These bolts threaded perfectly into the existing mount on my skid steer, and the Grade 8 rating gives me confidence they won't snap under heavy loads. The yellow zinc coating looks good too.

Zoe Z. ★★★★★

These threads cut clean and the yellow zinc coating is uniform across every single bolt, no bare spots or drips. My machine frame came together solidly with zero stripped heads, so the Grade 8 hardness is definitely there where it counts.

Steven ★★★★★

The hex head on these Grade 8 bolts grabbed my socket perfectly without any stripping, and the yellow zinc coating looks clean. They’re holding my heavy equipment mount rock solid, and being USA-made gave me extra confidence in the steel quality. Exactly what I needed for a critical repair job.
