FAQ

Q: How do I know if a spring is left hand or right hand wound?

---The best way to determine the direction of the spring is to use your right index finger and lay it over the spring.

If the end of the spring starts at the tip of your right index finger and proceed to wrap towards your palm,

this is considered a right hand wound spring. On the contrary, a left hand wound spring would start at

the tip of your left index finger and wrap towards your left palm.

Q: Dose it matter if a torsion spring is left or right hand would?

---Yes. A torsion spring should be coiled so that the spring would wind up as a load is applied.

If the spring unwinds as a load is applied it should probably be coiled in the opposite direction.

Q: What is the proper deflection of a spring?
---Deflection refers to the distance a compression spring is compressed, the distance an extension spring in extended,

and the distance a torsion spring is rotated. Every spring is designed with a certain amount of sage deflection.

If a compression spring is compressed more than its safe deflection the spring will begin to take a set,

and not to come back to its original height. If an extension spring is extended beyond its safe deflection

the spring will begin to increase in length as it is returned to its original position. The same is the case with a torsion spring,

if it is wound beyond its safe deflection it will take a set and not unwind to its original starting position.
