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. Button socket cap screws offer a wider bearing surface and high tensile strength but are still low profile like other socket cap screws. Button Head Socket Cap Screws are designed for light duty applications such as securing guards, covers, and ornamental fixtures. Button Heads present a pleasing appearance to an assembly.
