Customer Reviews (4.8 / 5 · 5 reviews)

Victoria ★★★★★

The square neck on these grabbed the wood instantly and never spun a millimeter while I torqued them down, which is exactly what you want from a carriage bolt. All 30 arrived with clean threads and no rust spots, and the plain steel finish is fine for my indoor framing project.

Sofia ★★★★★

Installed these on a heavy-duty gate, and the 28-inch length gave plenty of bite into the post. The plain steel finish is holding up well so far, no rust in the first few weeks.

John A. ★★★★★

The square neck grabbed into the wood perfectly on my deck frame, no spinning at all while I tightened the nut. These 28-inch plain steel bolts feel solid and straight, just what I needed for heavy timber connections.
