Also known as tension or expansion springs, extension springs are tightly wound coils that create tension when a load or force is applied to their ends, causing them to extend. These springs usually feature hooks, loops, or end coils, which are often the weakest points. In high-force applications, replacing hooks with bolts can prevent bending or breaking, thereby increasing the spring's durability and reliability. Extension springs are used in devices where a force pulls apart the spring from its original length, such as trampolines, push and pull levers, rocking horses, and screen doors. The primary function of an extension spring is to provide extended force when stretched and to return to its original position when the force is removed.
