Customer Reviews (4.8 / 5 · 5 reviews)

Eli ★★★★★

The fully threaded design made it easy to get a solid grip when fastening a bracket into wood, and the 316 stainless finish feels sturdy enough for outdoor use. Arrived well-packed and exactly as described.

Adam ★★★★★

I've been using these bolts for a metal gate assembly and the 316 stainless steel is holding up much better against salt air than standard hardware I've tried. The full threading along the entire shank made it easy to get a solid grip in thick brackets.

Joshua K. ★★★★★

Used these for a dock repair where corrosion resistance matters, and the 316 stainless held up perfectly through a week of salt spray. The fully threaded design made them easy to snug into tight spots on the aluminum frame.
