These U-Bolts with nyloc nuts & washers are designed to suit your 61mm round trailer axle. Easy to install, simply clamp down the trailer axle onto the spring suspensions by tightening the U-Bolts over the axle and securing them onto the fish plates using the nyloc nuts. For safety precautions, re-tighten the nyloc nuts on the U-Bolts every 300km. With a zinc finish, these U-Bolts are built to last due to its corrosion resistance.
