1/2″ Gal Round U Bolts are generally 1/2 inch or 12.5mm for 1500kg axles. Our U-bolts are tested to destruction which occurs at 17,000kg.
U bolts are used to clamp axles used to trailers, caravans, and campers.
Importantly, to prevent clamp failure, tighten u bolts after 300 kilometers.
Gal Round U Bolts are manufactured from mild steel and stretch as they set after the initial tightening.
During tightening, once the fishplate begins to bend, the u-bolts are tight.
Finally, expect to gain 1/4 or 1/2 a turn when retightening after 300 kilometers.
