Deck screws get their name because their most common application is to secure deck boards to the main beams. Trim head stainless steel deck screws differ from a standard bugle head, in that the diameter of the screws head is significantly smaller, and the countersink is a flat head instead of a bugle. These features are designed to make the screw head less noticeable on the finished application when installed.
