DIN 127 Spring Lock Washer is a ring split at one point and bent into a helical shape. This causes the washer to expert a spring force between the fastener’s head and the substrate, which maintains the washer hard against the substrate and the bolt thread hard against the nut or substrate head. DIN 127 Spring Lock Washer creates more friction and resistance to rotation. Applicable standards are ASME B18.21.1, DIN 127 and NASM 35338 (formerly MS 35338 and AN-935).
