Customer Reviews (5.0 / 5 · 5 reviews)

Ava H. ★★★★★

The partially threaded shank is perfect for when I need a solid grip against the frame before the threads bite. All fifty bolts came out of the bag uniformly coated, no rust or burrs on any of them.

Charlotte ★★★★★

The zinc plating on these bolts gives them a nice, consistent finish that resists rust well. I needed a precise unthreaded grip length for a jig I was building, and the partially threaded shank worked perfectly for that. They threaded into my tapped holes smoothly without any binding.

George ★★★★★

The unthreaded grip section sits flush in the clearance hole, which made aligning the bracket much easier than with fully threaded bolts. Zinc coating looks uniform and no rust after a few humid days. Only wish the threads were a touch longer for thicker nuts.
