DIN 7980 Phosphor bronze Spring Lock Washers with Square Ends for Cheese Head Screws

The DIN 7980 Spring Lock Washers with Square Ends made of phosphor bronze are designed specifically for cheese head screws. They are made of high-elastic phosphor bronze material and come in specifications ranging from M3 to M24. Their unique square-end structure can effectively grip the screw head and provide continuous locking force in vibration environments. Jinghong Fasteners ensure that the washers maintain a stable elastic modulus through precise stamping and heat treatment processes, and are widely used in fields such as electrical appliances, instruments, and communication equipment where high reliability of anti-loosening is required.

Phosphor bronze material has excellent elasticity and wear resistance. The square end design precisely fits the groove of the cheese head screw, preventing rotation and loosening. Jinghong standard parts adopt progressive die stamping technology, with a size accuracy of ±0.02mm. They cover all specifications from M3 to M24 and support non-standard customization.
