Value Collection 31486 Flat Washer Vulcanized Fiber 25 Pack

Product Description

The VALUE COLLECTION 31486 is a standard flat washer made from vulcanized fiber with a plain finish. It features an inside diameter of 0.875 inches, an outside diameter of 1.3125 inches, and a thickness of 0.093 inches. Vulcanized fiber construction provides electrical insulation and resistance to abrasion, making this washer suitable for applications where metal washers would create a grounding or conductivity risk. Technicians in electrical, HVAC, plumbing, and general mechanical trades install these washers where non-metallic fastener hardware is required. Each package contains 25 washers.

This washer is designed for use in applications requiring a non-conductive, non-metallic load-distribution fastener component. Vulcanized fiber is commonly specified in electrical panel assemblies, control board mounting, and mechanical assemblies where metal contact must be avoided. The plain finish makes it suitable for interior or protected installations. It meets the MIL-I-24768 fastener standard and is referenced under UNSPSC code 31161807. Sold in packs of 25 to support small-batch service work and maintenance applications.

Installation Notes

Installation is performed by licensed electricians, HVAC technicians, or mechanical tradespeople depending on the application. Always de-energize and lock out the circuit or equipment before installing washers in or near electrical assemblies. Verify that the inside diameter and thickness are appropriate for the fastener and mating component before installation. Do not use plain-finish vulcanized fiber washers in outdoor or high-moisture environments without additional protective measures.
