Customer Reviews (5.0 / 5 · 5 reviews)

Charlotte ★★★★★

The square neck grabbed instantly when I torqued them into oak—no spinning at all, which is exactly what you want from a carriage bolt. These 3/4-10s are fully threaded, so I had plenty of length to work with on a 5-1/2" joint, and the plain steel finish is clean. Solid value for a ten-pack.

Leo ★★★★★

Finally found carriage bolts beefy enough for heavy timber framing—the square neck under the head really does bite into the wood and stop spinning, a huge help when working alone.

Aurora S. ★★★★★

Had to rebuild a section of my deck railing and the square neck on these bolts grabbed perfectly into the pressure-treated wood, no spinning. The rounded head gives it a nice clean look too.
