Customer Reviews (5.0 / 5 · 5 reviews)

Riley ★★★★★

These fit perfectly in my tractor's mower deck spindles and the partial threads made installation a breeze. The hex heads grabbed nicely with a socket wrench without stripping.

Avery E. ★★★★★

The yellow zinc finish on these held up perfectly through a week of outdoor use without a hint of rust, and the partial threading really helped my alignment during assembly. For a thousand pieces at this price per unit, they're a solid value for any shop stock.

Hannah ★★★★★

Finally found bolts that actually fit my heavy equipment without stripping the threads. The yellow zinc coating is holding up well against the weather, and having a full box of 1000 means I won't run out mid-project.
