Disc 4mm

A disc with a 4mm thickness typically refers to a flat, circular object or component that measures 4mm in its diameter from one edge to the opposite edge through its center. Discs of this size are used in various applications, including mechanical assemblies, electronics, filtration systems, and industrial processes where precise thickness and diameter measurements are crucial. They can be made from different materials such as metal, plastic, or composite materials, depending on the specific requirements of the application.
