Springs are available in different types. By definition, a spring is an elastic device that's capable of storing mechanical energy. When exposed to a force, it will deform while simultaneously storing mechanical energy. There are wire springs, however, and there are flat springs.They both consist of energy-storing elastic devices, but they feature different designs.

Wire springs and flat springs aren't the same. Wire springs are made of metal wire and feature a coil-like design. Flat springs are made of flat metal stock and feature a flat design.

When compared to flat springs, wire springs offer increased travel. They can extend or compress longer distances. Flat springs, though, typically support heavier loads. They won't break or otherwise sustain damage. Even when used with heavy loads, flat springs will continue to store mechanical energy.

Flat springs are often used in conjunction with fasteners. They can prevent fasteners from loosening, in fact. Normally, vibrations can cause fasteners to loosen. Exposure to vibrations may force a bolt or screw out of the hole in which it was installed. But a flat spring can secure the bolt or screw in place. You can use the flat spring like a washer around the screw or bolt.
