Phillips Flat Head Machine Screws

Oct 11, 2023 1

Thread type: Countersunk cross head machine screws usually use standard thread structures, such as UNC, UNF, etc., to connect with other threaded components.

Countersunk head design: The head of a countersunk screw is designed to be flat or slightly concave, allowing it to be embedded into the material surface, achieving a smooth installation surface and avoiding interference from protruding parts on surrounding components.
