DIN 127 M24 Spring lock washer

DIN 127 M24 is a spring lock washer, on a M24 × 2 mm metric thread. A split helical spring washer intended to resist loosening. Worth knowing that independent testing has repeatedly found its locking effect is marginal once the joint is properly preloaded — for safety critical joints use a prevailing torque nut instead.
