NUT 1-1/4-7 HVY HEX JAM GR-8 (JLG JL88501120)

A damaged nut can compromise the security of a bolted joint, leading to loosening under vibration. During assembly, a heavy hex jam nut of this grade provides a locking function against a primary fastener. The part type is a Grade 8 heavy hex jam nut with a 1-1/4-7 thread size. Its plain mechanical function is to be tightened against another nut or a bearing surface to prevent rotation. A concrete generic failure consequence is that an undersized or incorrect nut may strip threads, causing the assembly to separate. Keeping a nut in sound condition helps maintain clamp load in critical connections. Verify the serial number or application, then call (562) 693-7748. This aftermarket replacement part references JLG catalog number JL88501120. The item ships at approximately 0.44 pounds.
