What is a dome head screw?
Dome Head Screws have a round top with a flat underside. They sit above the work surface and tend to be used when requiring a more decorative finish.

Closely related to the carriage bolt is the timber bolt (also called mushroom-head bolt and dome-head bolt), meant to fasten wood to wood (rather than metal to wood), for use with large wood planks and structures. It has a domed head that is proportionally wider than that of a carriage bolt.
