Thomas ★★★★★

I needed a bulk supply for a deck repair project, and these 5-1/2" carriage bolts gave me exactly the length I needed to go through thick pressure-treated lumber. The fully threaded shaft made installation smooth, and the square neck kept them from spinning while I tightened the nut.

Lucy ★★★★★

The square neck under the head seated perfectly into the wood, so I didn’t need a wrench to hold them still while tightening. Got through a whole fence line with the 450 count and still have plenty left over for repairs.

Aurora ★★★★★

Needed a lot of these for a deck project, and the fully threaded design made them grip the wood perfectly without any slipping. The rounded head sits flush and looks clean, plus the square neck really does its job keeping everything tight.
