Extension springs are designed to absorb and store energy as well as create a resistance to a pulling force. It is initial tension that determines how tightly together an extension spring is coiled. This initial tension can be manipulated to achieve the load requirements of your particular application. All Century extension springs are wound with an initial tension force which offers a small deflection load for secure installation "holding". The initial tension is equal to the minimum force required to separate adjacent coils. Each spring is of the constant diameter type with a variety of hook/loop styles.

We have been specializing in the main production of various compression springs, extension springs, helical springs, torsion springs, rubber springs, disc springs, spiral springs, leaf springs, shaped springs, and various springs. 

Q: Is there a minimum order quantity?

A: We have a $25 minimum order requirement.

Q: What does “load” stand for?
A: The load specifies the maximum safe weight in pounds to use on the spring. Using more load will cause the spring to be overstressed.

Q: How can I tell stainless steel and carbon steel apart?
A: The best way is to use the spark test. With a hand rotary tool, gentle touch the spring to the sanding plate. If the spring sparks, it is carbon steel. To learn more follow the link below to our blog post about materials.

Q: How do you cut one of the cut to length springs?
A: For smaller wire diameters, a hand help nipper will work. However, large wire diameters should be cut with an abrasive cut off wheel.
