Compression Springs are used primarily for storing and returning mechanical energy. This page lists the industries and assemblies where they are specified, the selection criteria that matter for each application, installation practice, and the cases where a different fastener type is the correct choice. Parts are supplied to ISO / DIN. Stocked across roughly 0.6 mm to 5 mm, they cover light-duty and instrument-scale work.
Typical Applications for Compression Spring — ISO / DIN (Series 141)
The most common settings where these are specified:
- 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.
- General machine building: fastening covers, brackets, motors and sub-assemblies on production equipment.
How to Specify Compression Spring — ISO / DIN (Series 141) for Your Application
- Size: Select on wire diameter, and confirm it against the mating feature in the assembly. This product spans 0.6 mm–5 mm; 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 is a trade-series article rather than one covered by a published dimensional standard, so dimensions can differ between manufacturers. Quote the dimensions you need — or the part you are replacing — rather than a standard number.
Where Compression Spring — ISO / DIN (Series 141) 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.
Custom manufacturing · Made to drawing
Need a compression spring outside the standard range?
A non-standard spring is quoted from the drawing; where one already exists in the catalog, the special is usually a variation on its tooling.
Minimum order from 2,000 pieces; samples within 7 days of drawing approval.
