Customer Reviews (4.4 / 5 · 5 reviews)

Avery ★★★★★

I needed a full box of these for a pergola project and the square neck under the head held perfectly in the pre-drilled holes, making assembly much easier. The zinc plating looks clean and should resist rust well for outdoor use.

Joseph I. ★★★★★

I used these carriage bolts to secure a workbench frame, and the 4-inch length grabbed perfectly into the pressure-treated wood. The coarse threads on the 3/8-16 size made driving them in smooth and easy, even with a socket wrench in tight spots.

Joseph W. ★★★★★

I needed a full box of these for a deck repair and the 4-inch length was exactly right for sandwiching two 2x4s. The zinc plating looks clean and uniform, and all 50 came out of the package without any bent threads or damaged heads.
