Value Collection 42482 External Tooth Lock Washer M10

Product Description

The VALUE COLLECTION 42482 is an external tooth lock washer designed for use with M10 screws. It features serrated external teeth that bite into the mating surface and fastener head to resist loosening from vibration and torque. Made from spring steel with a zinc-plated finish for basic corrosion resistance, this washer has an inside diameter of 10.77mm, an outside diameter of 18.0mm, and a thickness of 0.9mm. It is a standard hardware component installed by mechanics, millwrights, electricians, HVAC technicians, and general trade professionals wherever a secure, vibration-resistant fastening point is required.

This external tooth lock washer is suited for light to medium-duty bolted assemblies in residential, commercial, and industrial applications. Typical uses include panel mounting, equipment frames, electrical enclosures, HVAC cabinet assembly, and general mechanical fastening where an M10 bolt or screw is used. The serrated tooth profile provides positive locking action without requiring thread-locking compounds. This washer is sold in a minimum order quantity of 100 pieces per order.

Installation Notes

Install this washer between the fastener head and the mating surface with the teeth facing the fastener head or the work surface as required by the assembly. Ensure both mating surfaces are clean and free of debris before assembly to allow full tooth engagement. Do not reuse lock washers that have been fully compressed or deformed, as tooth engagement will be reduced. This is a general hardware component requiring no special tools beyond standard hand tools or power drivers.
