Customer Reviews (4.8 / 5 · 5 reviews)

Sebastian J. ★★★★★

I needed some heavy-duty bolts for a piece of farm equipment, and the 3-inch length on these was just right. The hex head made them easy to drive with a socket, and the threads cut cleanly into the steel.

Brian E. ★★★★★

The hex heads on these bolts fit a socket perfectly, and the yellow zinc finish looks clean and professional. They threaded smoothly into my equipment frame without any binding. Solid hardware for the price.

Violet ★★★★★

I needed some heavy-duty bolts for my shop press, and these 3-inch hex heads fit perfectly with no wobble. The yellow zinc finish looks great and should hold up well against rust in my garage.
