SS Spring Lock Washer (Type B):3.1 - DIN 127/A2

This SS Spring Lock Washer (Type B) is a fastener accessory machined from stainless steel to provide corrosion resistance in demanding environments. It conforms to the DIN 127 standard and is graded as Property class A2, indicating its specific alloy composition and mechanical characteristics. The nominal diameter of 3.1mm defines its physical size for compatibility with specific bolt shanks. Buyers select this component to secure fasteners against vibration-induced loosening, offering a reliable locking mechanism that outperforms standard flat washers in dynamic applications. When choosing a size, select the 3.1mm nominal diameter to match the thread size, while the A2 grade ensures suitability for general stainless steel applications where extreme chlorine exposure is not the primary concern.
