Customer Reviews (4.4 / 5 · 5 reviews)

Brian ★★★★★

I needed heavy-duty bolts for a deck repair and these 5/8-11 x 9-1/2" carriage bolts were just the right length to go through the thick beam. The square neck seated nicely into the wood as I tightened them, and the plain steel finish looks clean and industrial.

Hazel R. ★★★★★

The square neck pulled tight into the wood just like it should, so no spinning when I tightened the nut. These carriage bolts feel solid and the 9-1/2 inch length was exactly what I needed for my pressure‑treated lumber project.

Matthew ★★★★★

These bolts fit perfectly into my deck frame, and the square neck grabbed the wood instantly so I didn't need a second wrench to keep them from spinning. The 5/8-inch thickness feels solid for heavy loads, and the nine-and-a-half-inch length was just right for sandwiching two beams.
