Customer Reviews (5.0 / 5 · 5 reviews)

Harper F. ★★★★★

The partial threading on these Grade 5 bolts made aligning the heavy machinery frame much easier than with fully threaded ones. The yellow zinc coating looks tough and hasn't shown any rust after a week in a damp shop.

Riley T. ★★★★★

Bought these to replace some worn bolts on a press we have at the shop. Threads are clean and the zinc coating looks like it’ll hold up well. Fit right into our existing equipment without any fuss.

Olivia A. ★★★★★

Needed some seriously strong bolts for a press build, and these grade 5 hex heads drove in perfectly with a socket—no stripping at all. The yellow zinc finish looks clean and should hold up well in a shop environment.
