Forward Controls Design 4140 Billet Castle Nut - Black Nitride - CNF IMR Powders And unlike other tools onThe original MIL SPEC castle nut is a hard product to improve upon, but Forward Controls Design has proven it is not impossible. The CNF is based on the original technical data package specification for the castle nut but does offer several improvements. Deeper staking notches make for much more secure staking. Even installation is improved with the coarse serrations making threading it down to the endplate easier and more comfortable. Features: 4140
