Description
An SQ Med SPR washer (Square Medium Spring washer) is a specialized split lock washer with a square cross-section, commonly used to provide tension and prevent fasteners from loosening due to vibration. The zinc-plated finish offers a sacrificial protective layer against corrosion, making them suitable for indoor and light outdoor mechanical applications Technical Specifications These washers are typically manufactured to industrial standards to ensure consistent performance in mechanical assemblies. Standard Compliance: Most models conform to DIN 7980, the standard for single-coil spring washers with square ends. Material: Generally manufactured from Spring Steel to provide the necessary resilience and "spring-back" force. Common Sizes: Available in various metric sizes, including M6, M8, M10, M12, M16, and M20. Load Distribution: Unlike flat washers that merely distribute load, the square section of these spring washers is designed to bite into the nut and the mounting surface, providing a secure locking mechanism.- Key Benefits and Applications Vibration Resistance: Ideal for automotive engines, construction equipment, and machinery where constant movement could otherwise unscrew standard bolts. Corrosion Protection: The zinc plating prevents rust and oxidation, extending the service life of the connection compared to bare steel. Cost-Effectiveness: Zinc-plated versions are more affordable than stainless steel while still providing sufficient durability for non-marine environments
