NUT - 3/8 LOCK PLASTIC (Genie GN4828)

A damaged lock nut can allow threaded fasteners to loosen under vibration, leading to mechanical misalignment or component separation. The Genie catalog reference GN4828 identifies this aftermarket replacement part as a 3/8 lock nut with a plastic insert. Its primary function is to resist loosening by creating friction against the bolt threads. The plastic insert deforms slightly during installation, providing a prevailing torque that maintains clamping force. A common failure consequence is that a worn or missing lock nut may cause attached parts to shift or detach during operation. Keeping a lock nut in sound condition helps maintain secure fastening in assemblies subject to movement or vibration. Verify the serial number or application, then call (562) 693-7748.
