NUT - 3/8 LOCK PLASTIC (Bobcat BC87D000006)

A damaged lock nut can compromise the security of bolted connections, leading to loosening under vibration. During inspection, a nut of this type may show signs of plastic insert wear or thread deformation. The part is an aftermarket replacement for the Bobcat catalog reference BC87D000006. It functions as a 3/8 lock nut with a plastic insert that resists loosening from mechanical vibration. A common failure consequence is gradual fastener loosening, which can cause misalignment or component separation in assembled equipment. Keeping a lock nut in sound condition helps maintain consistent clamping force over time. Verify the serial number or application, then call (562) 693-7748.
