ARK MRUB4G Galvanised U Bolts are extra-long, square-shaped bolts designed for trailer and caravan mounting tasks that require deep reach and high clamping power. With a 60mm internal width and a full 135mm leg length, these U bolts are ideal for larger chassis beams, multi-layer clamping setups, and oversized suspension components.
Each U bolt features a 50mm threaded section and a rugged hot-dipped galvanised finish, providing excellent corrosion resistance for outdoor and marine use. Manufactured from 1/2" diameter steel, they’re tough enough to handle repeated stress and vibration under towing conditions.
Perfect for securing heavy brackets, axle plates, U-bolt fish plates, or frame extensions where standard-length bolts just won’t reach.
