Customer Reviews (4.8 / 5 · 5 reviews)

Richard ★★★★★

I needed some serious fasteners for a deck repair, and these 16-inch carriage bolts were long enough to go through thick beams without any trouble. The plain steel finish is exactly what I expected for the price, and the square neck kept them from spinning while I tightened the nuts.

Benjamin G. ★★★★★

Installed these on a heavy-duty swing set project and the 16-inch length gave plenty of bite through the beams. The square neck did its job, sinking in cleanly and keeping everything snug without spinning. Solid plain steel finish for the price.

Nicholas S. ★★★★★

The square neck grabbed perfectly into my lumber, no spinning at all while I tightened the nuts. These 16-inch bolts have serious heft and the plain steel finish is exactly what I needed for an outdoor project.
