Michael A. ★★★★★

These bolts threaded cleanly into my milling machine's T-slots without binding. The yellow zinc finish looks like it will hold up well against oil and chips.

Matthew C. ★★★★★

I needed some heavy-duty bolts for a trailer hitch repair, and the 7/8-9 thread cut cleanly into the old frame holes without any binding. The yellow zinc coating looks like it’ll hold up well against road grime.

Kevin G. ★★★★★

The partially threaded design made these cap screws grip perfectly for my equipment assembly project. They drove in smoothly with a socket wrench and the hex head didn’t strip at all. Solid fasteners for the price.
