NUT - 3/8 LOCK PLASTIC (JLG JL8305645)

A damaged lock nut can allow fastened components to loosen during operation, leading to mechanical misalignment or failure. This aftermarket replacement part references JLG catalog number JL8305645. The nut is a 3/8-inch lock type with a plastic insert that resists vibration-induced loosening. When the plastic locking element wears or deforms, the nut may no longer maintain clamping force under dynamic loads. Keeping a lock nut in sound condition helps preserve joint integrity in bolted assemblies. The item ships at approximately 0.018 pounds.
