Secure round axles, frame rails, and marine plumbing to 1.5-inch pipes or tubing with an extended-length, rust-resistant round bend U-bolt.

Bring heavy-duty clamping power to your trailer suspension, marine rigging, or utility plumbing with this premium Galvanized Round U-Bolt. Designed with a precise 1-3/4" inside width and a generous 4-3/8" inside length, this versatile fastener is engineered to wrap smoothly around standard 1.5-inch outer diameter round axles, structural tubes, or heavy conduits. The extended length provides plenty of clearance for thick mounting plates, leaf springs, or layered brackets. Hot-dip galvanized to survive relentless saltwater exposure, rain, and road grime, it delivers maximum corrosion defense where you need it most.
