Description of Shoulder Washer
A Shoulder Washer, also known as an insulating washer or sleeve washer, is a specialized type of washer with an extended cylindrical sleeve or shoulder that provides additional support or insulation. It is commonly used in applications where electrical insulation, spacing, or mechanical support is required. These washers prevent direct contact between fasteners and components, reducing the risk of electrical short circuits or wear.
