Left Hand Wound Spring

Find various sizes and angles of deflection in right hand wound and left hand wound torsion springs with straight legs and ends at grainger.

Left hand wound spring.

If it turns away from your fingers then you are looking at the left handed spring. If the last coil of the spring points in the same direction of your fingers then you are looking at the right handed spring. On the other hand a left hand winding spring is wound in an anti clockwise direction and has its end of wire on the left side. Lee spring stock torsion springs are offered with legs of.

There are many options for leg configuration so the spring can be attached in different ways. Alternatively if the cutoff torsion end is on the right hand side of the spring 3 o clock position then the spring is rhw. Usually you will have two springs on your door which will be color coded. The fingers should be placed on the outside of the body and your thumb should point upwards.

It is hard to tell the direction of winding from the front side. A left hand wound spring will spiral in the same direction as a left hand threaded screw. A right hand wound spring will spiral in the same direction as a right hand threaded screw. The wind of the torsion spring can be right hand left hand or double torsion.

It is important to specify either right hand wound or left hand wound for torsion springs. For compression and extension springs. If the cutoff torsion end is on the left hand side of the spring 9 o clock position then the spring is lhw. Torsion springs are designed and wound to be actuated rotationally and to provide an angular return force.

If a spring screws onto a thread the direction of the helix should match that of the thread. If the end of the spring wire in the 9 o clock position then the spring is left hand wound. The above drawing shows a left hand wound spring. You can easily determine it from the end of the spring.

Most of the time the end on the right hand wind is red and the left and wind is black as you can see on the graphic below. Common torsion spring uses include clothespins clipboards swing down tailgates and garage doors. The load should always be placed so that the spring is closing. Pick up your spring and look into it.
