Number of coils. Wire wound springs can be made very long, such as garter springs for example. The quantity of continuous wire available on the feed spool limits this spring’s length. Machined springs are limited to about 30 coils depending upon size, however, rarely are coil numbers above 20.

EXTENSION SPRINGS are found in garage door assemblies, vise-grip pliers, and carburetors as well as thousands of other places. When they are attached at both endsand when the components they are attached to moves apart, the spring tries to bring them together again.
Extension Springs are wound with initial tension known asstored energy which holds the coils together and offers resistance to a pulling force. Springs can have many different styles of ends, the most commontypes of loops and hooks are Machine and Crossover. They can be closed (loops) or open (hooks).
Machine End: Wire comes directly off the body, then forming a circle across the center
Crossover End: Wire comes across the center of the spring
Double Loop: end consisting of two coils with no gap between the coils and the end of the wire
TORSION SPRINGS can be found on door hinges, door locks and clipboards as well as thousands of other places. When the ends of the torsion spring are attached tothe component, and when these components rotate around the center of the spring in the direction that winds the coil, the spring tries to push them back to theiroriginal position. Torsion springs offer resistance to externally applied torque as the ends are rotated in angular deflection. Commonly used over an arbor or mandrelfor support. Torsion springs are subjected to bending stress rather than torsional. Normally close wound and are left hand or right hand wound.Torsion springs are selected based on the Degree of Deflection required: usually 90, 180, 270 or 360° from the spring body.
Length of Leg: the length of the torsion spring leg is measured from the center of the body to the end of the leg or tip
Direction of Wind: torsion springs should be used in the direction that winds the coil

Wall ties are metal connectors that bond the brick veneer to the structural framework of a building. They play a crucial role in maintaining the stability and integrity of the wall system. By anchoring the veneer to the support structure, wall ties help the brick withstand various forces, including wind, seismic activity, and even thermal expansion.
In a wire spring, the entire length of the wire contributes to the elasticity because the forces and moments are distributed end to end with the ends providing the interface with adjoining equipment.
