Value Collection LWHIS1250USA-010BX Split Lock Washer

Product Description

The VALUE COLLECTION LWHIS1250USA-010BX is a Grade 8 spring steel split lock washer sized for 1-1/4 inch screws. It features a zinc plated finish and is manufactured to inch system standards. The washer measures 1.254 inches minimum inside diameter, up to 1.28 inches maximum inside diameter, with a maximum outside diameter of 2.104 inches and a thickness of 0.384 inches. The split design bites into mating surfaces under load to resist loosening from vibration. Maintenance technicians, millwrights, and general tradespeople install these washers in bolted assemblies where fastener retention under dynamic or vibratory loads is required.

This split lock washer is suited for heavy-duty bolted connections in industrial, mechanical, and structural applications where a 1-1/4 inch fastener is used. The Grade 8 material rating indicates high tensile strength, making it appropriate for demanding load-bearing assemblies. It does not meet military specifications. Typical applications include equipment mounting, machinery assembly, and structural fastener joints in shop or field environments.

Key Features

• Grade 8 spring steel construction for high tensile strength and reliable load retention
• Zinc plated finish provides basic corrosion resistance in general-duty environments
• Split lock design creates mechanical interference to resist fastener back-out under vibration
• Inside diameter range of 1.254 to 1.28 inches fits standard 1-1/4 inch screw shanks
• Maximum outside diameter of 2.104 inches suits standard bearing surface requirements
• Inch system dimensions for straightforward integration with standard inch-series fasteners

Compatibility

Designed for use with 1-1/4 inch screws and bolts in inch-series fastener assemblies requiring a split lock washer with Grade 8 spring steel construction.

Installation Notes

Install this washer between the fastener head or nut and the mating surface, with the split gap positioned to allow the washer to flatten fully as the fastener is tightened. Ensure mating surfaces are clean and free of debris before assembly. Follow applicable torque guidelines for the fastener grade and size per the relevant mechanical or structural specification for the assembly. Do not reuse lock washers that have been fully flattened or deformed from prior service.
