Value Collection R83920226 Split Lock Washer 7/8 in

Product Description

The VALUE COLLECTION R83920226 is a split lock washer sized for 7/8-inch screws and fasteners. Manufactured from 18-8 stainless steel, it provides reliable corrosion resistance in wet, outdoor, and chemically exposed environments. The washer functions by exerting spring tension against the fastener and mating surface when the assembly is torqued down, resisting loosening caused by vibration and thermal cycling. Inside diameter ranges from 0.887 to 0.905 inches, outside diameter ranges from 1.464 to 1.494 inches, and overall thickness is 0.219 inches. This part is suited for mechanical, plumbing, HVAC, and electrical panel assembly work where a standard carbon steel washer would be inadequate due to moisture or chemical exposure.

This split lock washer is used in a wide range of trade and industrial applications requiring a 7/8-inch fastener seat. Common install scenarios include pipe flange assemblies, equipment mounting brackets, electrical enclosure hardware, and structural connections subject to vibration. The 18-8 stainless steel construction makes it appropriate for outdoor installations, coastal environments, and applications where contact with water or mild chemicals is expected. Installers working in HVAC equipment rooms, plumbing chases, and poolside mechanical areas will find this washer suitable for use wherever a standard steel lock washer would corrode prematurely.

Key Features

• 18-8 stainless steel construction resists corrosion in wet and chemically exposed environments
• Split lock design applies spring tension to resist fastener loosening from vibration and thermal cycling
• Inside diameter range of 0.887 to 0.905 inches fits standard 7/8-inch screw shanks
• Outside diameter range of 1.464 to 1.494 inches provides broad bearing surface
• Thickness of 0.219 inches delivers consistent locking force without excessive stack height
• Inch system of measurement for direct compatibility with standard SAE fastener tooling

Compatibility

Designed for use with 7/8-inch screws and bolts in standard inch-series fastener assemblies across mechanical, plumbing, HVAC, and electrical applications.

Installation Notes

Install using standard SAE hand tools. Place the split lock washer between the fastener head or nut and the mating surface before tightening. Ensure the split ends seat flush against both surfaces as the fastener is torqued down. Inspect washers for deformation or flattening before reuse, as a fully compressed split lock washer no longer provides effective locking force.
