Product Description

The VALUE COLLECTION LWHIS0620USA-025BX is a Grade 2 spring steel split lock washer designed for use with 5/8-inch screws and fasteners. The split ring design applies tension under the fastener head or nut, resisting loosening caused by vibration and torque relaxation. With a zinc plated finish, this washer provides basic corrosion resistance suitable for general-purpose indoor and light-duty applications. The inside diameter measures 0.628 inches minimum to 0.641 inches maximum, and the maximum outside diameter is 1.087 inches. Thickness is 0.188 inches. This package contains 25 washers and is sold as a single package quantity.

This split lock washer is used in mechanical assembly, structural fastening, and equipment maintenance across HVAC, plumbing, electrical, and general industrial applications. It is suited for residential and light commercial installations where a 5/8-inch fastener is used and vibration resistance is required. Installers typically use these washers on equipment mounting bolts, panel fasteners, and pipe hanger hardware. The inch measurement system and standard Grade 2 designation make this a common general-purpose hardware item stocked by trade professionals for service and retrofit work.
