Customer Reviews (4.8 / 5 · 5 reviews)

Eva ★★★★★

Installed these on a new deck railing, and the square neck grabbed perfectly—no spinning at all. The 12-inch length was exactly what I needed for the thick beams.

Ava W. ★★★★★

Used these to fasten a heavy wooden gate and the square neck grabbed the wood perfectly, zero spinning while I torqued them down. The 12-inch length gave plenty of bite through the 4x4 post. Solid feel to the steel, no rust spots out of the package.

Thomas K. ★★★★★

Needed some serious hardware for a deck repair, and these 12-inch carriage bolts were exactly the heavy-duty solution I was after. The plain steel finish feels solid and substantial, and the square neck really did lock them in tight so I could torque them down without spinning.
