Value Collection LWIS0-6USA-500BX No. 6 Split Lock Washer

Product Description

The VALUE COLLECTION LWIS0-6USA-500BX is a No. 6 split lock washer designed to resist fastener loosening under vibration and dynamic loads. Stamped from uncoated bright steel, it features a helical split that bites into the mating surface as the fastener is tightened, creating a spring-loaded locking action. The inside diameter ranges from 0.141 to 0.148 inches, the outside diameter ranges from 0.25 to 0.266 inches, and the washer measures 0.031 inches thick. Licensed tradespeople and assembly technicians use this washer in electrical panels, light mechanical assemblies, and general fastening applications where a No. 6 screw is specified.

This split lock washer is suited for light-duty residential and commercial fastening tasks. It pairs with No. 6 machine screws in electrical enclosures, equipment panels, junction boxes, and structural assemblies requiring secure, vibration-resistant connections. The bright uncoated steel finish is appropriate for dry interior environments where corrosion exposure is minimal. This SKU is sold as a box of 500 pieces, making it a practical quantity for shop stock or ongoing service work.

Installation Notes

Install split lock washers between the fastener head or nut and the mating surface with the split ends oriented to bite into both surfaces as the fastener is tightened. Follow applicable NEC or equipment manufacturer torque guidance when used in electrical enclosures. Do not reuse a washer that has been fully compressed flat, as it will no longer provide effective locking action. Use in dry interior locations only, as the uncoated steel finish offers no corrosion resistance in wet or outdoor environments.
