Customer Reviews (4.8 / 5 · 5 reviews)

Hannah ★★★★★

Threads went in cleanly on the equipment frame, and the zinc coating is holding up well in a slightly damp shop. The partial threads grabbed tight on the first pass, no binding. Solid 50-count box for the price.

Nicholas ★★★★★

These headed right into a vibrating piece of equipment and haven't budged a bit; the yellow zinc finish makes them easy to spot during maintenance. The partial threading grabbed perfectly for the deep draw I needed on that flange assembly.

Adam ★★★★★

The yellow zinc coating on these Grade 5 bolts matched perfectly with the existing hardware on my tractor attachment, and the partial thread let me get a solid bite into the frame. I torqued them down to spec without a single issue.
