Value Collection LWHIS075USA-025BX Split Lock Washer

Product Description

The VALUE COLLECTION LWHIS075USA-025BX is a Grade 2 spring steel split lock washer designed for 3/4 inch screws and bolts. The split ring design applies continuous tension against the fastener and mating surface, resisting loosening caused by vibration and dynamic loads. With an inside diameter of 0.753 inches and a maximum outside diameter of 1.285 inches, this washer seats cleanly against standard 3/4 inch fastener heads. The bright uncoated finish suits interior or controlled-environment applications where corrosion resistance is not a primary requirement. Installers in HVAC, plumbing, electrical, and general mechanical trades reach for this style of washer when a positive locking action is needed without thread-locking compounds.

This split lock washer is used in residential and commercial mechanical assemblies wherever 3/4 inch threaded fasteners require vibration resistance. Typical applications include equipment mounting, panel attachment, pipe hanger assemblies, and structural connections in both new construction and service work. The inch-measurement dimensions make it a direct fit for standard imperial fastener systems. Sold in a minimum order quantity of 25 pieces per box, this washer suits both single-job service calls and ongoing shop stock replenishment.

Key Features

• Grade 2 spring steel construction provides consistent bite and clamping force under load
• Split ring profile generates axial tension that resists fastener back-out from vibration
• 0.753 inch minimum inside diameter fits standard 3/4 inch screws and bolts without modification
• Bright uncoated finish — no coating to crack, chip, or interfere with electrical grounding paths
• Inch measurement system — direct replacement for imperial fastener assemblies
• Minimum order quantity of 25 pieces supports both service-call use and bench stock

Compatibility

Designed for use with 3/4 inch imperial-measure threaded fasteners in standard mechanical, electrical, and plumbing assemblies. Does not meet military specifications.

Installation Notes

Split lock washers are installed by licensed electricians, HVAC technicians, plumbers, and pipefitters as part of standard fastener assemblies. Place the washer between the fastener head and the mating surface before torquing the bolt or screw. De-energize equipment and isolate any pressurized systems before accessing fastener locations in live assemblies. Do not reuse a washer that has been fully compressed flat, as the spring action will not recover.
