Joshua F. ★★★★★

These are the first 1/2-20 bolts I've bought that didn't need a trip to the hardware store to chase the threads. The yellow zinc finish is even and the partial threading makes them perfect for clamping down on thick steel plates without bottoming out.

Mia ★★★★★

The hex heads sat flush in my wrench without any stripping, and the yellow zinc finish has a nice, even coating that looks clean on the equipment. Threaded section gave me plenty of grip for the frame mount, and the 25-count box will last me a while.

Jacob ★★★★★

The partially threaded design made installing a locking nut much easier than fully threaded bolts would have. These grade 5 screws feel solid and the yellow zinc finish looks clean.
