JConcepts 4mm large flange serrated locknuts
JConcepts have new 4mm large flange serrated locknuts available. The high precision wheel nuts are designed with a large flanged area for additional support against the wheel and serrated for locking security while the large flange and clamping surface area supports the wheel and helps maintain geometry during flex and load. The larger area also provides more footing for the serrated area which provides a more comfortable lock-down. The lightweight locknuts are available in blue and black colour and can be used on a wide range of 1/10th cars, buggies and trucks.
