Compression Springs are used primarily for storing and returning mechanical energy. This page summarizes where they fit, the industries that rely on them, and the practical points to get right when you specify them — to DIN 2098. Stocked across roughly M0.5 to M10, they cover general to heavy-duty work.
Typical Applications for Compression Springs
The most common settings where these are specified:
- Maintenance & repair (MRO): a stocked size for servicing existing plant where the original fastener spec must be matched.
- Fabrication & metalwork: bench and on-site assembly of steel frames, enclosures and weldments.
- Mechanisms & latches: return and detent forces in moving assemblies.
- Valves & actuators: controlled closing or opening force.
- Vibration & cushioning: absorbing shock and maintaining contact pressure.
How to Specify Compression Springs for Your Application
- Size: Match the nominal size to the mating thread or hole. This product spans M0.5–M10; check the full table below for the exact dimensions of each size.
- Material: Choose the material and finish for the service environment — plated steel for general use, stainless for corrosion resistance.
- Environment: For damp, coastal or chemical exposure prefer A4/316 stainless or a suitable coating; indoors, plated steel or A2 is usually sufficient.
- Standard: This product is supplied to DIN 2098. Quoting the standard on your order guarantees interchangeable dimensions between suppliers.
Where Compression Springs Are Not the Right Choice
Not where a precise, repeatable force is needed without rating the spring, and avoid over-stressing beyond the rated deflection.
