Brass is surprisingly strong but a very soft metal. Brass screws also demand a carefully sized pilot hole to avoid installation breakage. Brass is the traditional choice for a non-corrosive metal and provides a classic look and feel to any project. The Round Head has a semi-elliptical top surface with a flat bearing surface underneath. The flat bearing surface allows for lateral movement (as opposed to a Flat or Oval Head that have a countersunk bearing surface that will self-center in the mounting holes) when attaching hardware. Generally chosen for it's traditional appearance. |
