- Purpose: Split ring lock washers prevent nuts, bolts and screws from vibrating loose in demanding assemblies. - Design: The washer is split at a specific point and bent to form a helical shape, creating spring pressure when installed. - How it works: When tightened, the washer adds extra pressure to the nut or bolt and the mating surface, increasing resistance to rotation and helping maintain clamp force. - Holding power: The edges of the split can bite into the nut and surface, supplying additional retention and reducing loosening in dynamic conditions. - Materials and sizes: Available in a variety of materials and size options to fit different fasteners and applications. - Performance: Improves retention under vibration, shock and thermal cycling without added complexity or moving parts. - Compatibility: Designed for use with nuts, bolts and screws in standard fastening applications where lock retention is needed. - Use scenarios: - Automotive or engine assemblies where vibration can loosen fasteners over time. - Industrial machinery and equipment subjected to constant motion or shocks. - Outdoor equipment and other installations exposed to environmental or thermal cycling stresses. - Selection guidance: Choose a size that matches the screw, bolt or nut being used, and select a material suited to the operating environment to balance strength and corrosion resistance.
