65mm Square U-Bolt | 165mm – 175mm Length | 1/2″ BSW Thread

Hot-Dipped Galvanised | Includes Galvanised Nylock Nuts & Washers

Secure your axle with precision using our heavy-duty 65mm Square U-Bolt. This versatile hardware is designed to fit 65mm square axle profiles and provides the essential clamping force required for heavy-duty trailer suspensions.

With a length range of 165mm to 175mm, this U-bolt is perfect for thicker leaf spring stacks or for use with additional spacers and fish plates. The hot-dipped galvanised finish makes it the ultimate choice for boat trailers or any application where maximum corrosion resistance is a priority.

Key Features

Precision Fit: Designed specifically for 65mm square axles, ensuring a flush and secure fitment that prevents axle rotation.
Heavy-Duty Length: The 165mm–175mm reach provides ample clearance for multi-leaf spring packs and heavy-duty mounting plates.
1/2″ BSW Thread: Featuring a 50mm thread length in 1/2″ British Standard Whitworth, providing a robust, high-torque fastening solution.
Marine-Grade Protection: Hot-dip galvanising offers superior protection against saltwater and rust compared to standard zinc plating.
All-In-One Kit: Each U-bolt comes complete with a Galvanised Nylock Nut and Flat Washer, providing a vibration-resistant finish that won’t shake loose on corrugated roads.
