Customer Reviews (4.6 / 5 · 5 reviews)

Madison W. ★★★★★

The threads cut cleanly on these when I used them to bolt down some heavy equipment base plates. The partial threading made alignment easier than fully threaded bolts I've used before.

Steven N. ★★★★★

The zinc coating on these hex cap screws is thick and even, with no flaking or thin spots I could see. Installed them on a piece of heavy equipment and they torqued down smoothly without any thread binding. Solid purchase for the price.

Benjamin U. ★★★★★

Zinc coating looks even and uniform across all 60 pieces, and the partial threads leave plenty of solid shank for clamping down heavy equipment. These bolts feel properly heat-treated, not soft like some hardware store junk.
