Daniel ★★★★★

Yellow zinc finish is holding up great after a week bolting down a piece of heavy shop equipment, and the partial threads let me get full bite without bottoming out. Grade L9 steel feels seriously stout for the price.

Avery W. ★★★★★

The hex head grabbed my socket perfectly, and the partially threaded design made installation on my press brake a breeze. These Grade L9 alloy steel screws feel rock solid for heavy equipment assembly.

Hazel W. ★★★★★

These bolts are exactly what I needed for rebuilding a piece of farm equipment; the yellow zinc coating seems like it'll hold up well against moisture. The partially threaded design made aligning everything much easier than fully threaded ones I've used before.
