Value Collection 31464 Flat Washer Vulcanized Fiber 50 Pack

Product Description

The VALUE COLLECTION 31464 is a standard flat washer made from vulcanized fiber with a plain finish. It features an inside diameter of 0.281 inches, an outside diameter of 0.500 inches, and a thickness of 0.046 inches. Vulcanized fiber construction provides electrical insulation and resistance to solvents and oils, making this washer suitable for applications where metal washers would create a short circuit or corrosion risk. Each package contains 50 washers. This fastener hardware is installed by electricians, maintenance technicians, and mechanical assemblers across a range of light-duty industrial and electrical applications.

This washer is well suited for use in electrical enclosures, control panels, and mechanical assemblies where insulation between metal surfaces is required. The plain finish and fiber material make it appropriate for low-voltage electrical applications and general-purpose mechanical fastening where non-conductive spacing or cushioning is needed. It conforms to MIL-I-24768 and 27 GEE-F standards, which cover vulcanized fiber and composite laminate materials including G10 and FR-4 grades.

Compatibility

Designed as a standard flat washer for use with fasteners requiring a non-conductive fiber spacer or insulating washer in electrical and general mechanical assemblies conforming to MIL-I-24768 and 27 GEE-F specifications.

Installation Notes

Installation is performed by electricians and mechanical technicians as part of fastener assembly. De-energize and lock out all electrical circuits before installing or replacing insulating washers in electrical enclosures or control panels. Vulcanized fiber washers should not be over-torqued, as the material can compress and crack under excessive clamping force. Follow applicable NEC guidelines when using insulating hardware in electrical panel assemblies.
