About This Product

These Flat Head Machine Screws are constructed of steel, which is a magnetic material that provides strength for everyday fastening applications. They have a zinc plated finish, which provides mild corrosion resistance and a shiny finish. They also have a Phillips drive, which has a cross head design to prevent slippage. They have a 12-24 thread size and a 1/2 in shank length. They have a flat head, which is less visible than other head styles when installed because it does not protrude from the material surface. They meet ANSI B18.6.3 specifications. Pack of 100.
