NUT - HEX JAM 7/8-14 (Hyster HY161685)

A damaged hex jam nut can compromise the security of a threaded fastener assembly. During inspection, a 7/8-14 hex jam nut may show signs of wear or thread damage. Keeping this nut in sound condition helps maintain clamping force in bolted connections. This aftermarket replacement part references the Hyster catalog number HY161685. The nut type provides a plain mechanical function of locking a primary fastener against loosening. A concrete generic failure consequence is that a loose jam nut can allow the primary fastener to back out under vibration. Verify the serial number or application, then call (562) 693-7748.
