Adam R. ★★★★★

These are exactly as specified, the yellow zinc coating looks even and the partial threads give a solid bite when torquing down. Opening a box of 800, I did a quick spot check on a few and every one threaded clean into a standard nut. For the price per piece, you can’t beat it for production work.

Richard ★★★★★

I needed a bulk supply for assembling some heavy-duty shelving, and the hex head design made these easy to drive with a socket wrench. The yellow zinc coating looks consistent across all 800 pieces, which is a nice touch for corrosion resistance.

Michael I. ★★★★★

The partially threaded design made these perfect for aligning the mounting plate on my press brake. They seated cleanly with a socket and the Grade 5 steel feels solid under torque. Exactly what my old machinery needed.
