Value Collection 31483 Flat Washer Vulcanized Fiber 0.75 in Id 25pk

Product Description

The VALUE COLLECTION 31483 is a standard flat washer made from vulcanized fiber with a plain finish. It measures 0.75 inches inside diameter, 1.125 inches outside diameter, and 0.046 inches thick. Vulcanized fiber offers electrical insulation, moisture resistance, and mechanical toughness in a lightweight, non-metallic form. These washers are used to distribute load, provide insulation, or act as a buffer layer between fasteners and mating surfaces. Licensed electricians, maintenance technicians, and mechanical assemblers commonly install this type of washer in panel assemblies, enclosures, and equipment where non-conductive hardware is required. Each package contains 25 washers.

This washer suits applications where metallic contact must be avoided, such as grounding isolation, vibration dampening, or protection of soft substrates from fastener damage. The vulcanized fiber material meets MIL-I-24768 and 27 GEE-F (G10; FR-4) fastener standards, making it appropriate for use in electrical and electronic assemblies, industrial equipment, and military-grade or commercial-grade hardware installations where compliance with those specifications is required.

Key Features

• Vulcanized fiber construction provides electrical insulation and mechanical durability
• Plain finish with no coating, suitable for direct use without surface treatment concerns
• Meets MIL-I-24768 and 27 GEE-F (G10; FR-4) fastener standards
• Compact 0.046-inch thickness for tight clearance assemblies
• Sold in a pack of 25 for bench stock and small-batch jobs

Compatibility

Designed as a standard flat washer for use with 3/4-inch fastener applications requiring a non-metallic, electrically insulating washer conforming to MIL-I-24768 and 27 GEE-F (G10; FR-4) specifications.

Installation Notes

Install using standard hand tools appropriate for the fastener size. Ensure mating surfaces are clean and free of burrs that could crack or deform the fiber material. Vulcanized fiber washers should not be over-torqued, as the material is susceptible to compression damage under excessive clamping force. Power down any electrical assembly before servicing fasteners in energized enclosures.
