Value Collection LW7S02000-100BX M20 Split Lock Washer

Product Description

The VALUE COLLECTION LW7S02000-100BX is a metric split lock washer designed for use with M20 fasteners in steel bolted assemblies. Manufactured from uncoated steel with a bright finish, this DIN 127B-standard washer provides resistance to fastener loosening caused by vibration and dynamic loads. The split (helical spring) design bites into mating surfaces under clamp load, maintaining joint integrity over time. With a minimum inside diameter of 20.2mm, a maximum outside diameter of 33.6mm, and a thickness of 4mm, this washer is dimensionally consistent with standard M20 hardware. It is sold in a minimum order quantity of 100 pieces and is commonly specified by maintenance technicians, industrial assemblers, and mechanical contractors.

This washer is suited for general-purpose bolted connections in industrial, commercial, and mechanical applications where M20 fasteners are used. Typical installation scenarios include structural steel connections, machinery assembly, pipe flange bolting, and equipment mounting where vibration resistance is required. The uncoated bright steel finish makes it appropriate for indoor or protected environments. It does not meet military specifications, making it best suited for standard commercial and industrial fastening applications rather than defense or aerospace work.

Installation Notes

Installation is performed by mechanical assemblers or maintenance technicians using standard hand or power tools. Always ensure the mating fastener and bearing surface are clean and free of debris before seating the washer. Position the washer between the nut or bolt head and the clamping surface with the split gap oriented away from the joint face. Follow applicable torque specifications for the fastener grade and joint design per the relevant mechanical or structural standard governing the assembly.
