Customer Reviews (4.8 / 5 · 5 reviews)

Elizabeth X. ★★★★★

The yellow zinc finish is evenly applied and the threads are clean, so they drive in without any hiccups. I bought these for a skid loader attachment build and the Grade 8 rating gives me confidence they'll hold up under real strain.

Evelyn ★★★★★

Installed these on a heavy-duty conveyor frame and they torqued down perfectly without stripping. The hex heads are crisp and the threads ran smooth all the way in. For 125 pieces this pack felt like a solid value.

Lily A. ★★★★★

The yellow zinc finish on these Grade 8 bolts looks sharp and evenly applied, which made them easy to spot in my parts bin. They threaded into my equipment mounts without any binding, and the hex heads grabbed cleanly with a socket every time. Solid US-made fasteners for the price.
