Daniel F. ★★★★★

Used these on a heavy-duty equipment mount and the threads caught smoothly right from the start. The yellow zinc coating looks uniform and should hold up well against moisture. Solid buy for the price.

Jason ★★★★★

I needed Grade 8 bolts for a trailer hitch repair and these 1/2-20 x 1-3/8" fully threaded fasteners fit perfectly. The yellow zinc coating looks clean and the threads ran smooth with no binding.

Ellie V. ★★★★★

The hex head design on these Grade 8 bolts makes them easy to torque with a socket, and the yellow zinc coating feels durable. They fit perfectly for a heavy-duty equipment repair I was doing.
