1/2-20 Button Head Cap Screws
Button Head Socket Cap Screws are commonly used in machine parts, die fixturing, and clamping. The socket head enables driving where there is not sufficient space for wrenches or sockets. The button shaped head offer a wider bearing surface. Button head socket cap screws have a high tensile strength but are still low profile. They are covered by ASME B18.3
