Customer Reviews (4.8 / 5 · 5 reviews)

Robert C. ★★★★★

The square neck on these #3 carriage bolts grabbed the wood immediately, no spinning while I tightened them. The zinc plating looks clean and even across all 200 pieces, and they drove in straight for my whole framing project.

Michael ★★★★★

Put these on a wooden gate frame and the square neck grabbed perfectly in the pilot hole, no spinning. The zinc coating looks clean and should hold up fine outdoors.

Violet P. ★★★★★

Used these to bolt down some metal brackets for a workbench frame and the zinc coating looks clean after a week in a damp garage. The threads caught smoothly and the dome heads give a nice finished look.
