The Lock Washer provides tension and resistance at the fastener joint used to mount the refrigerant condenser cover bracket. When compressed during tightening, the washer helps maintain clamping force and prevents the fastener from backing off due to vibration, thermal expansion, or repeated cycling. It supports stable bracket engagement by reducing joint movement and helping keep the cover firmly positioned. By maintaining consistent fastener preload, the Lock Washer helps protect the condenser cover mounting area from loosening, misalignment, or unnecessary stress over time.Attributes:• Helps maintain fastener tension in the condenser cover mounting bracket.• Reduces loosening caused by vibration or repeated cycling.• Supports consistent clamping force at the fastener joint.• Helps keep the bracket securely positioned during operationApplications: The Lock Washer is installed under the fastener head used to secure the refrigerant condenser cover mounting bracket. It helps maintain tension, reduce loosening, and ensure reliable bracket retention under vibration and temperature‑related conditions.
