The metal lock washer is a widely used fastener component designed to prevent loosening of screws or nuts from vibration or changes in torque under different load conditions, maintaining the tightness of joints or assemblies. It achieves this function by exerting a locking force against the threaded parts when a tightening torque is applied or when tension forces are encountered due to uneven settlement or stress on the assembly, ensuring consistent clamping forces and stability across multiple orientations and applications. This lock washer comes in various sizes to cater for diverse screw or bolt dimensions while maintaining compatibility with different materials, threads, and thread pitches that might be used. Made from high-grade steel, the 1.24 ID (for Metric M3, M4 or #6 screws) and 2.30 OD washer is ideal for general fastening applications requiring strong securement in woodworking, machinery, automotive and various construction projects while resisting corrosion from moisture or chemical exposure.
