1/2 INCH ROUND U-BOLTS

1/2 Inch Round U-Bolts – Imperial-Sized Hardware for Round Trailer Axles

These 1/2 inch round U-bolts are designed to clamp round trailer axles to leaf springs or mounting pads using fishplates. Made for imperial-sized axle setups, they’re ideal for trailers built with non-metric axle standards.

Each U-bolt comes with nuts and flat washers, and is available in a range of lengths to suit various round axle diameters. Options in galvanised finishes help resist corrosion in marine or coastal environments.

Heavy-duty, precise fitment, and shipped Australia-wide.
