Value Collection 741096PS Lock Washer M8 8.4mm Id Spring Steel

Product Description

The VALUE COLLECTION 741096PS is an external tooth lock washer designed for use with M8 screws. It features a 8.4mm inside diameter and a 15mm outside diameter, with a thickness of 0.8mm. Constructed from Grade 2 spring steel with a zinc-plated finish, this washer provides reliable resistance to loosening under vibration and dynamic loads. The external tooth design bites into both the fastener bearing surface and the mating material, creating a mechanical lock that resists rotation. Licensed electricians, millwrights, pipefitters, and general mechanical trades use external tooth lock washers as standard hardware in panel assemblies, equipment mounting, and structural fastener applications.

This lock washer is suited for light to medium-duty fastening applications where vibration resistance is required. It is commonly used in electrical enclosures, HVAC equipment mounting, light structural assemblies, and general mechanical hardware installations. The zinc-plated finish provides basic corrosion protection suitable for indoor and dry or mildly humid environments. This washer is sold individually per package, with a minimum order quantity of 200 pieces, making it appropriate for shop stock, maintenance inventory, or production-line use.

Key Features

Compatibility

Designed as a standard external tooth lock washer for use with M8 screws and bolts in general mechanical, electrical, and light structural fastening applications.

Installation Notes

Installation is performed by general mechanical, electrical, or maintenance trades as part of standard fastener assembly. Place the washer between the fastener head or nut and the mating surface, with the teeth facing the fastener bearing surface. Ensure the mating surface is clean and free of debris before assembly. Do not reuse lock washers that have been fully compressed or deformed, as locking effectiveness is reduced.
