Value Collection R63082486 Lock Washer 10 Screw Ss 410

Product Description

The VALUE COLLECTION R63082486 is a No. 10 screw external tooth lock washer manufactured from Grade 410 stainless steel. The external tooth design bites into both the mating surface and fastener bearing face to resist loosening caused by vibration and dynamic loads. With an inside diameter of 0.204 inches and an outside diameter of 0.41 inches, this washer is sized for No. 10 fasteners across a wide range of light-to-medium duty mechanical assemblies. At 0.025 inches thick, it adds minimal stack height while delivering reliable locking performance. Electricians, HVAC technicians, plumbers, and mechanical contractors install these washers wherever vibration resistance is required in a corrosion-resistant fastening application.

This washer is suited for use in residential and commercial installations where stainless steel hardware is specified for moisture or corrosion exposure. Typical applications include electrical panel and equipment enclosure fastening, HVAC equipment mounting, plumbing fixture assemblies, and general sheet metal work requiring a No. 10 screw with positive anti-rotation retention. Grade 410 stainless steel provides good corrosion resistance in mildly aggressive environments and is commonly specified where mild chemical exposure or outdoor service conditions are present.

Key Features

Compatibility

Designed for use with No. 10 screws in external tooth lock washer applications requiring Grade 410 stainless steel hardware.

Installation Notes

Install this washer between the fastener head and the mating surface with the teeth facing the bearing surface to achieve proper locking engagement. Ensure the mating surface is clean and free of coatings that could prevent tooth engagement. Apply fastener torque per the fastener manufacturer specification for the screw size and material combination in use. Do not reuse lock washers once they have been compressed and removed, as the tooth geometry will not re-engage reliably.
