Compression Spring Coil Directions

Coil Direction: Compression springs can be left- or right-hand coiled.

To determine the compression spring coil direction, hold the compression spring with its axis on a horizontal plane. If the direction of the coil, from top to bottom, can be simulated by bending the index finger of the left hand, the coil is left-hand wound; if it can be simulated by the index finger of the right hand, the coil is right-hand wound.

Spring Engineers Tip: If the compression spring will be mounted on a bolt, right-hand winding is preferable.
