#10-32 Silicon bronze machine screws with round head and slotted or straight slot drive. Semi-elliptical round head with flat bearing surface underneath 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.

This style screw is generally chosen for it's traditional appearance. Silicon bronze offers great corrosion resistance and along with the slot drive provides the classic look of traditional boatbuilding.
