Miles ★★★★★

For a large deck project I needed bolts that wouldn't spin while tightening, and these carriage bolts have the square neck that grabs the wood perfectly. All 250 came in good shape, threaded clean, and they're plain steel which is exactly what I wanted for indoor framing.

Abigail ★★★★★

I needed a solid batch for building a heavy-duty gate, and these carriage bolts didn't disappoint—the plain steel finish is exactly what I expected for the price. The 7-1/2 inch length gave me plenty of thread engagement through thick lumber.

Christopher X. ★★★★★

The square neck grabbed the wood immediately and held tight while I tightened the nut, no spinning at all. For the price of a 250-pack, these are a solid workhorse for any framing project.
