Customer Reviews (4.8 / 5 · 5 reviews)

Emma ★★★★★

Used a handful to mount a heavy-duty jig on my mill table, and the 5/8-11 threads engaged cleanly without any binding. The Grade 8 rating gives me confidence they’ll hold up under serious load. Zinc plating looks even and shows no chips out of the bag.

Steven ★★★★★

The hex head makes it easy to really torque these down with a socket wrench, and the zinc plating seems like it'll hold up well in my shop. I replaced some worn-out bolts on a press with these, and they fit perfectly.

Olivia N. ★★★★★

I needed a rugged partially threaded bolt for a heavy equipment repair, and the 70-pack gives great value. These grade 8 zinc-plated caps fit the wrench perfectly and didn't strip under torque.
