SCREW,HEXAGON HEAD CAP (JLG JL4353890)

A damaged hexagon head cap screw can compromise the security of bolted assemblies. During inspection, a loose or missing screw may indicate prior vibration or improper torque. Keeping a hexagon head cap screw in sound condition helps maintain clamping force in fastened joints. This aftermarket replacement part references the JLG catalog and cross-references part number JL4353890. The screw type provides a plain mechanical function of securing components through threaded engagement. A concrete generic failure consequence is that a stripped or broken screw can allow joint separation under load. Verify the serial number or application, then call (562) 693-7748.
