Square Axle U-bolts 1/2

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.

U 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.
