Secure small-diameter round axles, marine pipes, and frame tubing with an extended-length, rust-resistant round bend U-bolt.

Engineered to deliver exceptional clamping force in tight spaces, this premium Galvanized Round U-Bolt is the ideal fastening solution for your marine, trailer, or industrial rigging projects. Featuring a precise 1-3/8" inside width and a generous 4-5/16" inside length, this specialized fastener is designed to wrap smoothly around standard 1-inch and 1-1/8" outer diameter round tubing, pipes, or light-duty axles.

Hot-dip galvanized for premium marine protection, it easily withstands saltwater, high humidity, and rugged road conditions.
