ISO 7380 Button Head Socket Cap Screws are fasteners characterized by a rounded, button-like head and a cylindrical, fully-threaded shaft. The distinctive feature of these screws is the socket drive recess in the head, allowing them to be tightened using a hex key or Allen wrench. These screws are commonly used in applications where a low-profile, aesthetically pleasing appearance is desired. The button head design provides a smooth and finished look while offering a reliable and secure fastening solution.
