Customer Reviews (3.6 / 5 · 5 reviews)

Harper C. ★★★★★

Used these to bolt down a heavy duty workbench and they torqued down smooth without stripping. The partial threading gave just the right grip for a 4" bolt, and the yellow zinc coating looks clean out of the box. Exactly what I needed for the job.

Zoe O. ★★★★☆

The yellow zinc finish held up well during installation without scratching off like cheaper coatings I've used. Threads were clean and the partial threading made alignment easier on the equipment I was working on. Only gripe is the lack of extra thread length for applications needing more engagement

Avery ★★★☆☆

The partially threaded design is handy for certain applications, but I wish the threads were a bit cleaner—a couple bolts had slight burrs. Still, for the price and USA-made quality, they get the job done fine on medium-duty projects.
