Customer Reviews (5.0 / 5 · 5 reviews)

Grace ★★★★★

The partial threading made tightening these into heavy equipment frames much easier since I didn't have to fight threads through the full length. The yellow zinc finish seems consistent and should hold up well against rust in my shop.

Julian S. ★★★★★

These bolts feel seriously stout in the hand, and the yellow zinc finish looks factory-fresh right out of the package. The partially threaded length gave me plenty of grip for a heavy equipment mount without any slop in the threads.

Ruby R. ★★★★★

The partially threaded design made these easy to start by hand, and the yellow zinc finish looks solid on my press. Torqued them down with a socket and they held perfectly.
