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. Spring rate is the amount of force required for every inch of compression. The higher the spring rate, the harder it is to compress the spring.
To determine the spring rate of a cut spring, first multiply the spring’s original length by the spring rate given, then divide the result by the cut length (in inches).

Corrosion-Resistant Compression Spring Stock
Made of stainless steel, these springs are more corrosion resistant than steel compression springs. Keep them 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. Spring rate is the amount of force required for every inch of compression. The higher the spring rate, the harder it is to compress the spring.
To determine the spring rate of a cut spring, first multiply the spring’s original length by the spring rate given, then divide the result by the cut length (in inches).

Extension Spring Stock
Keep these springs on hand so you can cut the right length whenever you need it. All have straight-cut ends, which allow you to bend the end coils into hook or loop 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. Spring rate is the amount of force required for every inch of extension.
To determine the spring rate of a cut spring, first multiply the spring’s original length by the spring rate given, then divide the result by the cut length (in inches).

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