Cap Screw ASME B18.3

A button head socket screw is a type of headless screw that has a rounded, button-shaped head. This design can provide a more aesthetic appearance and may also offer additional benefits, such as preventing the screw from turning easily under pressure. Button head socket screws are commonly used in applications where a finished appearance is desired, such as in furniture, machinery, and automotive components. They are typically driven with a socket wrench.
