Compression Spring Stock
Keep these extra-long springs on hand so you can cut the right length whenever you need it.
As you squeeze a compression spring, it pushes back to return to its original length. Rate is the amount of force required for every inch of compression. The higher the rate, the harder it is to compress the spring.
To determine the rate of a cut spring, first multiply the spring’s original length by the rate given, then divide the result by the cut length (in inches).

Extension Springs with Hook Ends
As you stretch an extension spring, it gets harder to pull. Minimum load is the amount of force required to start to extend the spring. Maximum load is the amount of force required to fully extend the spring. Rate is the amount of force required for every inch or mm of extension.
