About Extension Springs

Hold parts together with these extension springs. When the ends of the spring are attached to different parts and the parts are pulled apart, the spring stretches and pulls against the load in an effort to return to its original shape, bringing the parts together. The farther the spring is pulled apart, the greater the force it exerts on the attached parts. These springs are often found in equipment such as cots, garage door mechanisms, and vice-grip pliers.

For good reliability in precision applications, these extension springs have been manufactured to tight load and dimensional tolerances. They are made from music wire, which provides good strength and heat resistance in demanding applications with repeated cycles.
