1/2 inch Square U-bolts for Caravans, Campers and Boat Trailers

1/2 inch Gal Square U Bolts are rated at 1500kg single axle trailers, although our U-bolts are tested to destruction which occurs at 17,000kg.

The smaller rating allows for several factors, including shock loading events.

Measuring UboltsU bolts clamp axles used for trailers, caravans, and campers.

Significantly, to prevent clamp failure, tighten u-bolts after 300 kilometres.

Gal square U Bolts are manufactured from mild steel and stretch after the initial tightening.

Once the fishplate begins to bend during tightening, the u-bolts are tight.

Finally, expect to gain 1/4 or 1/2 a turn when retightening after 300 kilometres.

Why U-bolts may be the Major Cause of Accidents.

Stretching U-Bolts cause Caravanning Problems.
