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.

Suitable for applications where corrosive elements or high temperatures may be encountered, these stainless steel extension springs provide better heat and corrosion resistance than extension springs made from high carbon steel or music wire. They have been manufactured to tight load and dimensional tolerances for good reliability in precision applications.
