Customer Reviews (4.8 / 5 · 5 reviews)

Harper ★★★★★

I'm rebuilding a wooden gate and the square neck on these carriage bolts really digs in, stopping them from spinning when I tighten them down. The 316 stainless has held up well through a few weeks of rain without any rust spots appearing.

Olivia ★★★★★

Picked up a pack of these for a dock repair I've been working on, and the 316 stainless is exactly what you need for coastal exposure. The fully threaded design made driving them into the pressure-treated wood surprisingly smooth.

Thomas ★★★★★

The square neck on these grabs the wood instantly—no spinning, no swearing, which is rare for carriage bolts this size. The 316 stainless finish looks clean and has held up through a rainy week so far.
