DIN 127 M14 Spring lock washer

DIN 127 M14 is a spring lock washer, on a M14 × 1.5 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.
