The term is also used to describe any strong component designed to keep two objects closely linked together. Among the most common of these is the hurricane or seismic tie used in the framing of wooden structures. Also known as connector, structural connector, structural tie, and Simpson Tie. They are generally made of galvanized steel and designed to resist strong winds (including hurricane force winds). There are many different types of connectors; with a well known brand being manufactured by Simpson Strong-Tie.
Most ties have holes allowing them to be fastened to wood using nails of a designated size and type. Screws, which usually have a lower shear capacity than nails, are never used (except where noted). There are certain nails for certain ties.
Hangers have a 'seat' that a board (specifically joists and girders) rests on. They are most commonly used in floors, decks, and porches. If hangers are used the 'bowing' down of floor joists and girders is less likely to occur. They also give added strength to the connection.
