Customer Reviews (3.8 / 5 · 5 reviews)

Olivia F. ★★★★★

Got my deck frame all squared away—the square neck on these carriage bolts grabbed the wood perfectly so nothing spun while I was tightening. All 25 in the pack had clean threads and the zinc finish looks like it’ll hold up fine outdoors.

Stella X. ★★★★★

I needed some heavy-duty bolts for repairing a wooden gate, and these 1/2-13 x 7-1/2" carriage bolts are perfect. The zinc plating seems solid and the rounded head gives it a clean, finished look.

Ellie E. ★★★☆☆

The zinc coating looks decent, but three of the bolts had a bit of cosmetic spotting straight out of the package. They worked fine for a basic fence repair, though I'd probably go with stainless if appearances mattered more.
