Value Collection LWHIS162USA-010BX Split Lock Washer

Product Description

The VALUE COLLECTION LWHIS162USA-010BX is a heavy-duty split lock washer designed for use with 1-5/8 inch screws and bolts. Made from Grade 8 spring steel with a bright uncoated finish, this washer delivers reliable tension and vibration resistance in high-load fastening applications. The split helical design bites into the mating surfaces under torque, resisting loosening caused by vibration or thermal cycling. With an inside diameter of 1.633 inches, a maximum outside diameter of 2.694 inches, and a thickness of 0.045 inches, this washer meets DIN 127B and DIN 7980 standards. It is suitable for use by millwrights, maintenance technicians, and mechanical contractors working on heavy structural or industrial assemblies.

This split lock washer is intended for heavy-duty bolted connections requiring secure fastener retention in applications subject to dynamic loads, vibration, or repeated stress cycles. Typical installation scenarios include industrial machinery, structural steel assemblies, and heavy equipment maintenance. The inch measurement system and Grade 8 material grade make it appropriate for high-strength bolted joint applications where fastener loosening under load is a primary concern.

Key Features

• Grade 8 spring steel construction provides high tensile strength and consistent spring force under load
• Heavy-duty duty type rated for demanding bolted joint applications
• Meets DIN 127B and DIN 7980 standards for split lock washer geometry and performance
• Bright uncoated finish suitable for use in dry indoor or protected environments
• Inside diameter range of 1.633 to 1.663 inches accommodates standard 1-5/8 inch fastener shanks
• Helical split design generates axial load to resist fastener back-off from vibration

Compatibility

Designed for use with 1-5/8 inch screws and bolts in heavy-duty bolted assemblies. Conforms to DIN 127B and DIN 7980 dimensional standards for split lock washers in the inch measurement system.

Installation Notes

Installation is performed by millwrights, maintenance technicians, or mechanical contractors as part of a standard bolted joint assembly. Place the lock washer between the nut or bolt head and the mating surface before final torque is applied. Do not reuse split lock washers that have been fully compressed or deformed during prior service. Consult applicable industry standards or engineering specifications for torque requirements specific to the fastener grade and joint design.
