Secure your boat trailer frames, brackets, and crossmembers with a rugged, corrosion-resistant square bend U-bolt.

Ensure your marine trailer stays rock-solid under heavy loads with this heavy-duty Galvanized Square U-Bolt. Specifically engineered for mounting brackets, axles, bunks, and winches to square or rectangular trailer frames, this industrial-grade fastener provides a perfectly flush fit against flat steel surfaces. Hot-dip galvanized for superior corrosion resistance, it is built to survive continuous exposure to harsh saltwater, road grime, and intense humidity without rusting or losing its structural integrity.

Key Features

• Hot-Dip Galvanized Finish: Coated in a thick layer of protective zinc to deliver maximum rust and corrosion resistance in punishing marine environments.

• Precision Square Bend: Designed specifically to wrap tightly around square or rectangular steel tubing, preventing slipping, shifting, or frame damage under high torque.

• Heavy-Duty Thread Strength: Features standard, clean-cutting 1/2"-13 threads that handle high clamping forces and resist stripping during tight, secure installations.

• Complete Frame Security: Outlasts standard zinc-plated hardware, ensuring your trailer crossmembers and tongue components stay locked together season after season.
