Value Collection LWIS300USA-005BX Grade 8 Split Lock Washer

Product Description

The VALUE COLLECTION LWIS300USA-005BX is a Grade 8 spring steel split lock washer designed for use with 3-inch screws. It delivers reliable tension and vibration resistance in heavy-duty bolted assemblies. The washer features an inside diameter of 2.008 to 2.039 inches, a maximum outside diameter of 4.074 inches, and a thickness of 0.458 inches. The bright, uncoated finish leaves the base material exposed, making it suitable for applications where coating is applied after assembly or where bare steel is preferred. Licensed HVAC technicians, plumbers, pipefitters, and industrial maintenance professionals typically use lock washers of this grade in high-load, high-vibration environments.

This split lock washer is sized for 3-inch fasteners and is built to Grade 8 material specifications, indicating high strength and hardness suitable for demanding mechanical and structural applications. It is commonly used in commercial HVAC equipment frames, large piping support structures, electrical enclosure mounting, and other heavy industrial assemblies where fastener loosening due to vibration or thermal cycling is a concern. The uncoated finish allows for flexibility in post-installation treatment. Minimum order quantity is 5 pieces per order.

Installation Notes

Split lock washers should be installed between the fastener head or nut and the mating surface, with the washer seated flat before torquing. De-energize electrical systems and relieve pressure from piping or mechanical assemblies before performing any fastener work. Use calibrated torque equipment appropriate to the fastener grade and application. Confirm material and grade compatibility with the surrounding assembly before installation.
