Hannah T. ★★★★★

Needed a full box of partially threaded bolts for a jig I’m building, and the yellow zinc coating looks clean and even across all 175 pieces. The 6-inch length with the 3/8-16 thread cut exactly where I needed it, and they drove in smooth without any binding.

Samuel L. ★★★★★

The hex heads on these screws grip the socket perfectly, making assembly on my trailer hitch quick and hassle-free. The yellow zinc coating looks durable, and the partial threading gave me just the right shank length for a secure fit.

Leo ★★★★★

I needed a bulk supply of heavy-duty fasteners for mounting some shop equipment, and these 3/8-16 cap screws worked perfectly with a socket wrench. The yellow zinc coating gives them a clean, durable look that should resist rust well in my garage.
