Value Collection LWIS175GUSA-010BX Grade 8 Split Lock Washer

Product Description

The VALUE COLLECTION LWIS175GUSA-010BX is a Grade 8 spring steel split lock washer designed for 1-3/4 inch screws. It features a hot-dipped galvanized finish for corrosion resistance in demanding environments. The washer measures 1.778 inches minimum inside diameter, up to 1.81 inches maximum inside diameter, with a 2.688 inch maximum outside diameter and a thickness of 0.389 inches. Manufactured to DIN 127B and DIN 7980 standards, this washer is suited for structural fastening applications where vibration resistance and load distribution are required. Machinists, maintenance technicians, and mechanical contractors install this type of hardware in heavy-duty bolted assemblies.

This split lock washer is used in industrial, commercial, and heavy mechanical applications where 1-3/4 inch fasteners require positive locking under vibration or dynamic loads. The hot-dipped galvanized coating makes it appropriate for outdoor, wet, or corrosive environments where bare steel hardware would degrade prematurely. It is a standard inch-measurement washer conforming to DIN 127B and DIN 7980 specifications, making it a recognized choice for equipment assembly, structural steel work, and machinery maintenance.

Key Features

• Grade 8 spring steel construction provides high tensile strength and reliable locking force
• Hot-dipped galvanized finish delivers corrosion resistance for outdoor and wet service conditions
• Inside diameter range of 1.778 to 1.81 inches accommodates standard 1-3/4 inch screw shanks
• 0.389 inch thickness meets DIN 127B and DIN 7980 dimensional standards
• Split-ring design bites into mating surfaces under load to resist loosening from vibration

Compatibility

Designed for use with 1-3/4 inch screws and bolts in standard inch-measurement fastener assemblies conforming to DIN 127B and DIN 7980 specifications.

Installation Notes

Install between the fastener head or nut and the mating surface with the split ends positioned to bite into both surfaces as the fastener is tightened. Do not reuse split lock washers that have been fully compressed flat, as they will no longer provide effective locking force. Follow applicable mechanical or structural codes for proper fastener torque sequences when assembling bolted joints. Always ensure mating surfaces are clean and free of debris before installation.
