UDI RC M4 Hex Flanged Lock Nut

The UDI RC M4 Hex Flanged Lock Nut (part UDI-M02-003) is a straightforward UDI-branded spare for M4 threaded fixings on radio-controlled models. The hex profile allows tightening with standard tools, while the integrated flange provides a broader bearing surface to help distribute load. Its locking design helps resist loosening from vibration during running.

This practical hardware item is useful for routine maintenance and repairs, or to keep as a spare in your pit box. Use it wherever an M4 flanged lock nut is specified in your model’s manual or parts list. For precise fitment guidance, always refer to the documentation for your specific vehicle.
