Product description
The BH-7234-620 is a professional-grade 7/8-inch external lock washer designed for the heavy-duty assembly requirements of Challenger automotive lifts. This critical hardware component is engineered to provide a secure, vibration-resistant locking action for major structural bolts, ensuring that fasteners remain tightly seated under the dynamic stresses of vehicle lifting. Precision-manufactured with hardened serrations, it bites into the mating surfaces to prevent accidental loosening caused by mechanical vibration or thermal cycling. This high-strength washer is essential for maintaining the structural integrity and safety of the lift’s frame and carriage assemblies. As a direct-fit replacement for OEM part 40219, it is a necessary component for professional lift maintenance and installation projects.
