Value Collection 31482 Vulcanized Fiber Flat Washer 25-pack

Product Description

The VALUE COLLECTION 31482 is a standard flat washer made from vulcanized fiber with a plain finish. It features an inside diameter of 0.625 inches, an outside diameter of 1.000 inch, and a thickness of 0.062 inches. Vulcanized fiber provides electrical insulation, moderate mechanical strength, and resistance to solvents, making this washer suitable for applications where metal contact or conductivity must be avoided. Electricians, industrial maintenance technicians, and assembly workers commonly install this type of washer when isolating fasteners from conductive surfaces or protecting finishes under bolt heads and nuts.

This washer is suited for light-duty electrical and mechanical assemblies in residential, commercial, and industrial environments. It meets the MIL-I-24768 fastener standard and is also referenced under 27 GEE-F, G10, and FR-4 classifications, making it appropriate for panel assemblies, switchgear mounting, and printed circuit board hardware where non-conductive fastener hardware is specified. Each package contains 25 washers.

Installation Notes

Installation requires no special tools beyond standard hand tools appropriate to the fastener being used. Ensure the mating fastener and surface are clean and free of burrs that could crack or deform the fiber material. Vulcanized fiber washers are not rated for high-temperature environments — verify application temperature limits before installing. Power down or de-energize any electrical panel or assembly before installing fastener hardware.
