Metric Split Ring Lock Washers DIN 127-B - M6 (Pack of 1000) | High-Tensile Steel Anti-Loose Washers for Automotive, Machinery & Industrial Applications

Split ring lock washers are used to prevent nuts, bolts and screws from vibrating loose. Lock washers are split at a certain point and bent giving them a helical shape. In a variety of materials, these lock washers are pressed down adding extra pressure to the nut or bolt and material. This extra pressure creates a resistance to rotation. The edges or the split may add extra holding power by digging into the nut. Split ring lock washers are used where constant vibration occurs.
