Value Collection 31452 Flat Washer Vulcanized Fiber 1/8 in Id

Product Description

The VALUE COLLECTION 31452 is a standard flat washer made from vulcanized fiber with a plain finish. It features an inside diameter of 0.125 inches, an outside diameter of 0.250 inches, and a thickness of 0.031 inches. Vulcanized fiber is a dense, cellulose-based material valued for its electrical insulating properties, impact resistance, and dimensional stability under mechanical load. This washer is suited for applications requiring a non-metallic, lightweight spacer or insulating element in fastener assemblies. Machinists, electricians, and maintenance technicians commonly install this type of washer in light-duty mechanical and electrical assemblies where metal-to-metal contact must be avoided.

This washer is designed for use in applications where electrical insulation or vibration dampening between fastener components is required. Its small form factor makes it appropriate for precision instrument panels, PCB mounting, control enclosures, and similar assemblies in commercial and industrial settings. It meets the MIL-I-24768 and 27 GEE-F (G10; FR-4) fastener standards, making it suitable for defense and industrial specification work. This item is sold in packages of 50 pieces.

Key Features

• Vulcanized fiber construction provides electrical insulation and impact resistance
• Plain finish with no coating, suitable for applications requiring bare non-metallic contact surfaces
• Meets MIL-I-24768 and 27 GEE-F (G10; FR-4) fastener standards
• Inside diameter of 0.125 inches and outside diameter of 0.250 inches for precision fitment in small fastener assemblies
• Thickness of 0.031 inches for use as a thin spacer or insulating shim
• Sold in 50-piece packages for job-lot use

Compatibility

Designed as a standard flat washer for use with fasteners requiring a 0.125-inch inside diameter, appropriate for small-diameter screws and bolts in non-metallic or electrically isolated fastener assemblies.

Installation Notes

Installation is performed by hand or with standard assembly tools alongside the corresponding fastener. Ensure the washer is seated flat against the mating surface before torquing the fastener. Vulcanized fiber washers are not suitable for use in high-moisture environments or applications where prolonged water exposure is expected, as the material can absorb moisture and lose dimensional stability. No special tools or trade licensing are required for installation in typical fastener assemblies.
