Value Collection 31485 Flat Washer Vulcanized Fiber 50-pack

Product Description

The VALUE COLLECTION 31485 is a standard flat washer made from vulcanized fiber with a plain finish. It is designed to distribute load under fastener heads or nuts in assemblies where non-metallic, electrically insulating washers are required. With an inside diameter of 0.875 inches, an outside diameter of 1.1875 inches, and a thickness of 0.062 inches, this washer fits standard fastener applications across electrical, mechanical, and industrial assemblies. Electricians, maintenance technicians, and assembly professionals install this type of washer where metal contact or conductivity must be avoided. Each package contains 50 washers.

This washer is suited for use in electrical enclosures, panel assemblies, and equipment mounting applications where a non-conductive, non-metallic washer is required. Vulcanized fiber provides adequate mechanical strength and electrical insulation for a wide range of low-voltage and general-purpose fastening scenarios. It is commonly used in both light industrial and commercial electrical installations where code or design specifications call for insulating hardware.

Installation Notes

Installation is performed by electricians or mechanical assembly technicians following applicable NEC or equipment manufacturer guidelines. De-energize all circuits before installing washers in live electrical panels or enclosures. Hand-place the washer over the fastener shank before seating the nut or bolt head — do not use impact tools that may crack or fracture vulcanized fiber material. Inspect each washer for cracks or delamination before installation.
