Value Collection LWHIS112USA-010BX Split Lock Washer Grade 8

Product Description

The VALUE COLLECTION LWHIS112USA-010BX is a Grade 8 spring steel split lock washer sized for 1-1/8 inch screws and bolts. Split lock washers work by biting into both the fastener bearing surface and the mating material under clamp load, resisting loosening from vibration and torque relaxation. This washer carries a bright, uncoated finish and meets standard inch-system dimensional specifications. The inside diameter ranges from 1.129 to 1.153 inches with a maximum outside diameter of 1.903 inches and a section thickness of 0.345 inches. Machinists, millwrights, maintenance mechanics, and assembly technicians install these in structural and mechanical fastening applications where vibration resistance is required.

This split lock washer is suited for heavy-duty bolted joints in industrial, commercial, and mechanical assembly applications. The Grade 8 material rating indicates high-strength spring steel construction capable of maintaining tension under dynamic loading. Typical uses include structural steel connections, machinery mounting, equipment frames, and general MRO fastening tasks where a standard hex bolt or hex cap screw requires a locking element. The uncoated bright finish is appropriate for interior or protected environments where corrosion exposure is minimal.

Key Features

• Grade 8 spring steel construction for high-strength, high-tension fastening applications
• Split-ring design bites into fastener and mating surface to resist vibration-induced loosening
• Inside diameter range of 1.129 to 1.153 inches fits standard 1-1/8 inch screw and bolt shanks
• Maximum outside diameter of 1.903 inches and section thickness of 0.345 inches meet standard inch-series dimensional specs
• Bright, uncoated finish for clean installation in protected environments
• Inch system of measurement; does not meet military specifications

Compatibility

Designed for use with 1-1/8 inch nominal screw and bolt sizes in standard inch-series fastening assemblies.

Installation Notes

Split lock washers are installed between the fastener bearing surface (bolt head or nut) and the mating material before final torque is applied. Always confirm screw or bolt shank diameter matches the washer inside diameter before assembly. Do not reuse split lock washers that have been fully compressed flat, as the spring tension will be lost. Machinists and mechanical assemblers should follow applicable industry or equipment manufacturer torque specifications for the fastener grade in use.
