Definition of what is a coil spring?

A helical wound spiral spring that has circular coils made of round spring tempered wire. The coil spring has pitch or space throughout the center coils and tapered pitch on the ends known as closed and squared ends that are sometimes ground flat to enhance vertical straightness. Coils springs are used to compress and expel energy from the coil spring when compressed. Also known as compression springs. There are stock coil springs as well as custom coil springs. Here is an Example of a stock coil spring part number PC080-656-11500-MW-2800-CG-N-IN from access spring.
