Compression Spring Wire Dia 0.6mm Stainless Steel 5-305mm Length Pressure Small

Start with the bore or seat diameter in your assembly — the spring's outer diameter (OD) should be slightly smaller than the bore. Then select a free length that gives you the desired compressed and extended travel. Finally, match the wire diameter to the load requirement: 0.5 mm wire suits very light loads, while 0.6 mm wire handles slightly higher forces. Use the variant selector above to pick Wire Dia, OD, and Length.

These springs are designed for light-duty applications — pen mechanisms, sensor preloads, small actuator returns, and similar low-force tasks. For heavy-duty industrial actuators requiring high spring rates, a thicker wire diameter would be more appropriate. Contact us to confirm suitability for your specific load requirements.

Stainless steel offers good corrosion resistance in typical indoor and lightly humid environments. It is not recommended for prolonged immersion in saltwater or strong chemical solutions. For most DIY, electronics, and light automation applications, stainless steel provides reliable long-term performance without surface treatment.

Yes — the OD range of 3–12 mm covers a wide variety of standard spring seats. Ensure your housing bore is at least 0.1–0.3 mm larger than the spring OD to allow free movement. The closed ends provide stable seating on flat surfaces without additional retainers for most light-load applications.

Yes. The 0.5 mm and 0.6 mm wire diameters are commonly used in battery contacts, push-button mechanisms, and PCB-mounted spring contacts. The stainless steel material is non-magnetic and provides consistent contact force over many cycles, making it suitable for electronic assembly applications.

Wire diameter directly affects spring stiffness (spring rate). A 0.6 mm wire produces a stiffer spring with higher load capacity compared to a 0.5 mm wire of the same OD and length. If your application requires more resistance or a firmer return force, choose 0.6 mm. For very light preloads or delicate mechanisms, 0.5 mm is the better choice.

Each variant is sold as a pack of 10 pieces. This gives you spares for prototyping, testing, and replacements without needing to reorder immediately. The quantity is fixed at 10 pcs per pack across all size combinations.
