Customer Reviews (4.8 / 5 · 5 reviews)

Charlotte ★★★★★

The square neck under the head grabbed the wood instantly, so I didn’t have to wrestle with a wrench to keep them from spinning while I tightened the nuts. Threads were clean and cut all the way up, which made sinking them into my project quicker than I expected. For twenty heavy-duty bolts at this

Timothy ★★★★★

The square neck grabbed instantly when I tightened the first one, no spinning at all. These 5/8-inch bolts feel solid and the threading was clean all the way.

Brian Z. ★★★★★

Finally a set of carriage bolts where the threads run all the way to the head, so I could fasten a thick bracket without having to cut anything down. The rounded head sits flush and looks clean on the finished side.
