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.
