Customer Reviews (4.8 / 5 · 5 reviews)

Samuel H. ★★★★★

I needed these for a quick equipment repair and was glad to find a full 200-count package at this size. The hex heads seated cleanly with a socket driver without any stripping.

Mia ★★★★★

The yellow zinc finish on these is uniform and bright, and the threads cut cleanly on the first pass. For a 200-pack of grade 5 bolts at this price, they're a solid buy for general shop work.

Matthew M. ★★★★★

The hex heads on these bolts grabbed my ratchet perfectly without any slipping, which was a relief for a tight spot. Used them to secure a bracket to a steel beam, and the Grade 5 yellow zinc finish feels solid and corrosion-resistant. Exactly what I needed for heavy-duty fastening.
