FEATURES

DIN 127 B Split Lock Washers Flat Ends are split helical spring washers that are said to provide a spring-like take-up action and preload to resist thrust-induced loosening; these washers are designed for bolted joints with right-hand threads. When installed under the head they should be used with large heads like hex, pan and round. "Flat ends" means the bearing surface of the washer will be flat when fully compressed. For small diameter heads like socket head cap and cheese head screws, use high collar split lock washers. Available in spring steel, zinc plated and plain finish (susceptible to rust), stainless steel and spring bronze. The size of a washer is specified as its nominal hole size and should match the screw size (to illustrate, an M6 washer matches an M6 screw). DIN 127 B Split Lock Washers have a larger OD and are thinner than DIN 7980. DIN 128 A is recommended for new designs.
