Value Collection 013-9980070-1 Railroad Lock Washer

Product Description

The VALUE COLLECTION 013-9980070-1 is a railroad-pattern lock washer intended for use with 1-inch screws and bolts in heavy-duty fastening applications. Made from spring steel with an uncoated finish, this washer delivers reliable tension and vibration resistance under load. The inside diameter ranges from 1.0312 to 1.0625 inches, the maximum outside diameter is 2.0938 inches, and the thickness is 0.625 inches. The railroad washer profile provides a wider bearing surface than standard split-ring lock washers, making it suited for joints that require greater load distribution. Licensed tradespeople and maintenance professionals in rail, industrial, and structural applications typically install this hardware.

This railroad lock washer is used in applications where a 1-inch fastener requires positive locking and broad surface contact. The spring steel construction allows the washer to exert consistent clamping force after torque is applied, helping to resist loosening caused by vibration or thermal cycling. Typical installations include structural bolt assemblies, rail equipment maintenance, heavy machinery mounting, and industrial fabrication work where standard lock washers are insufficient for the load or environmental conditions.

Key Features

• Railroad washer profile provides wider bearing surface than standard split-ring designs
• Spring steel construction maintains clamping tension under vibration and thermal cycling
• Inside diameter range of 1.0312 to 1.0625 inches fits standard 1-inch fasteners
• Maximum outside diameter of 2.0938 inches for broad load distribution
• Thickness of 0.625 inches delivers substantial spring deflection under load
• Uncoated finish suitable for applications where coating compatibility or field treatment is required

Compatibility

Designed for use with 1-inch screws and bolts in railroad, structural, and heavy industrial fastening assemblies requiring a railroad-pattern lock washer.

Installation Notes

Installation is performed by millwrights, ironworkers, rail maintenance crews, or qualified mechanical trades. Always de-energize or isolate any powered or pressurized equipment before accessing fastener assemblies. Ensure the mating surfaces are clean and flat so the washer seats correctly and delivers uniform spring load. Do not reuse lock washers that show signs of flattening, deformation, or cracking.
