Socket Button Screws

Socket Button Screws have a domed head and are fastened into place using a Hex, Allen or Torx Key with the newer Torx drive giving a much more engaged drive where more torque can be applied. Also available with a flanged version that negates to need for a free spinning washer, whilst spreading the load more evenly across the service of the receiving material. Socket Head Button screws are aesthetically pleasing as they leave a smooth snag free surface. Available in metric and imperial sizes.
