Value Collection 31456 Standard Flat Washer Vulcanized Fiber

Product Description

The VALUE COLLECTION 31456 is a standard flat washer made from vulcanized fiber with a plain finish. It is designed for use as a load-distributing or insulating washer in mechanical assemblies, fastener applications, and light electrical or structural installations. The washer measures 0.187 inches inner diameter, 0.375 inches outer diameter, and 0.031 inches thick. Vulcanized fiber provides a combination of mechanical strength and electrical insulation properties not found in standard metal washers. Licensed tradespeople and assembly technicians working with small-fastener hardware install this part in both commercial and light industrial settings.

This flat washer is suited for use in applications requiring non-metallic, electrically insulating hardware. Its dimensions make it appropriate for use with No. 10 or 3/16-inch fasteners. The vulcanized fiber construction meets MIL-I-24768 and 27 GEE-F (G10; FR-4) fastener standards, making it applicable in military-spec and industrial-grade assemblies where insulating washers are specified. Sold in packages of 50 units, it is well-suited for maintenance, repair, and production operations that require consistent, small-quantity restocking of standard hardware.

Key Features

• Vulcanized fiber construction provides electrical insulation and moderate mechanical strength
• Plain finish with no coating, suitable for use in sensitive electrical or chemical environments
• Meets MIL-I-24768 and 27 GEE-F (G10; FR-4) fastener standards
• Compact profile at 0.031 inches thick for low-profile fastener assemblies
• Packaged in quantities of 50 for maintenance and production use

Compatibility

Designed as a standard flat washer for use with No. 10 or 3/16-inch fasteners in mechanical assemblies requiring non-metallic, insulating hardware that meets inch-system dimensional standards.

Installation Notes

Installed by maintenance technicians, electricians, or assembly personnel working on fastener-based assemblies. Ensure mating fastener diameter is compatible with the 0.187-inch inner diameter before installation. Vulcanized fiber washers should not be overtorqued, as the material can compress or crack under excessive clamping load. Store away from prolonged moisture exposure to preserve dimensional stability.
