Description
The DIN 127 Spring Washer is an essential, split-ring fastener that adheres to the widely recognized German Industrial Standard (DIN) 127. Its design is specifically engineered to counteract the forces that cause bolted joints to loosen, such as vibration, thermal cycling, and joint relaxation. Conforming to DIN 127 standards, this washer ensures consistent performance and durability in mechanical assemblies. Available in 304 or 316 stainless steel, it offers excellent corrosion resistance and mechanical strength, making it ideal for industrial, marine, and construction applications.
Features & Benefits
- Superior Corrosion Resistance: 304 and 316 stainless steel provide long-term protection against rust and oxidation in harsh environments.
- Helical Split-Ring Design: The split end-faces dig into the mating surfaces when compressed, providing a mechanical lock and increasing vertical tension for firmer locking.
- High Hardness & No Deformation: Maintains its shape and spring tension even under high-stress conditions, preventing loss of clamping force.
- Standard Concentricity: Ensures uniform load application around the fastener, protecting surfaces and ensuring optimal joint strength.
