Full Height – Full Strength

A Full Height Nylock Nut may be used in either tension or shear applications. The nylon insert serves as a retention device for the fastener, providing reliable locking without conventional locking washers.
Half Height – Save Weight

The Half Height Nylock Nut is typically selected for shear load applications. The thin design provides a limited number of threads, resulting in less strength when placed in tension. The nylon insert serves as a retention device for the fastener.
