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).

If you're designing something unique or can't find the exact size spring you need, we'll get it for you.
Zinc-plated steel springs have mild corrosion resistance.
Stainless steel springs have good corrosion resistance. They’re generally easier to compress than steel springs. Passivated stainless steel springs are more corrosion resistant than unfinished stainless steel springs.
Springs with closed and ground ends sit flat, so they won’t buckle.
To Order: Select a wire diameter in the material you need. Please specify: end type (closed ends, closed and ground ends, open ends, or open and ground ends), length, OD, and length between coils in 0.001" increments.

Plastic Compression Springs
A lightweight, nonmagnetic, and nonconductive alternative to metal springs, these plastic springs are better for corrosive environments and applications where metal springs cannot be used, such as in sensitive imaging equipment and machines where stray electrical current may cause damage.
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.

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).
