Round Head has a semi-elliptical top surface and a flat bearing surface. It is sometimes preferred over Pan Heads for its smooth surface and appearance. Machine threads are used in a pre-tapped hole with a nut. Zinc is a popular and economical plating and is a good choice for interior applications when working with acidic woods like red/white oak, or when the screw will be countersunk and plugged.
