The tooth lock washer is a type of mechanical fastener that helps secure components within the housing assembly. It prevents the loosening or rotation of nuts or bolts due to vibrations or other external forces commonly encountered in air conditioning systems. The toothlock washer gets its name from the small, tooth-like projections or serrations on its inner surface. These serrations are intended to bite into the mating surface of a nut or bolt head, creating a locking effect. Attributes:• Withstand the environmental conditions and temperature variations present in air conditioner housings• Maintain the tightness and integrity of the assembly, preventing the loosening of nuts or bolts due to vibrationsApplications:The Tooth Lock Washer is used in the air conditioning housing to enhance the locking effect by increasing the friction between the lock washer and the mating surface. By preventing unwanted movement, the tooth lock Washer helps maintain the stability and reliability of components within the air conditioner housing.
