Extension springs usually do not have any tolerance in between the threads. They absorb forces along the spring axis that work in an outward direction - the loads are usually static; in some cases, they can be exposed to high loads with a slightly variable force. They are always of a cylindrical shape.
Extension springs are often terminated by suspension eyes. Nevertheless, some of them can be made without them. Other special terminal pieces are then mounted on them.
