Customer Reviews (4.4 / 5 · 5 reviews)

Lucy ★★★★★

Needed a few for a trailer gate hinge repair, and the square neck under the head grabbed perfectly into the wood without spinning. The fully threaded length made installation quick.

Brian A. ★★★★★

I needed a full 5 inches of thread for a thick timber frame project, and these bolts delivered with consistent square necks that locked in tight from the first drive. No stripped heads or bent shafts in the whole box.

Edward Q. ★★★★☆

Got these for a fence repair and the 5-inch length gave me plenty of bite through the wood. They’re plain steel so you’ll want a coat of paint if they’re outdoors, but for the price per pack, they’re solid.
