Customer Reviews (4.6 / 5 · 5 reviews)

Ella ★★★★★

The square neck seats perfectly into the wood, so I didn't need a second wrench to hold these still while tightening. For a plain steel bolt, the threading is clean and uniform across all 100 pieces.

Natalie D. ★★★★★

These are solid bolts, the square neck really bites into the wood and keeps everything from spinning while you tighten the nut down. I used about half the package for a deck repair and every one seated perfectly.

Lucy J. ★★★★★

The square neck on these carriage bolts did exactly what it was supposed to—bit right into the wood and kept the bolt from spinning while I tightened the nut. All 100 in the package had clean threads and a consistent finish, no duds in the batch.
