304 Stainless Steel Compression Springs — 1mm Wire, 6mm OD, Reliable Elastic Force for DIY Builds

When your project demands consistent spring force in a compact form factor, undersized or mismatched springs cause binding, premature fatigue, and failed assemblies. Makers, hobbyists, and small workshop engineers working on precision mechanisms need springs they can trust across repeated cycles. These 304 stainless steel compression springs are engineered for exactly that — delivering reliable elastic return in a slender 1mm wire diameter and 6mm outer diameter profile.

Each spring is manufactured from 304 stainless steel wire with a wire diameter (CS) of 1mm and an outer diameter (OD) of 6mm. Free lengths range from 10mm (~0.39 in) up to 305mm (~12.0 in), giving you the flexibility to select the exact length your application requires. The coil pitch and spring rate vary by length; see variant options for precise load specifications.

These compression springs are well-suited for DIY electronics enclosures requiring button return mechanisms, small mechanical assemblies such as pen mechanisms and valve actuators, and light-load automation fixtures in maker lab or workshop environments where corrosion resistance is a priority.

⚙️ Compatibility: Fits guide rods or bores with inner diameter ≥ 6mm. Suitable for standard spring seats designed for 6mm OD compression springs. Select your free length from the SIZE variant above.

✅ Key Features of These 304 Stainless Steel Compression Springs

  • 🔩1mm Wire Diameter, 6mm OD — Compact cross-section fits tight spring pockets and guide pins in precision assemblies without binding.
  • 📏19 Length Options (10–305mm) — Choose the exact free length your design calls for, from short 10mm return springs to long 305mm travel springs.
  • 🛡️304 Stainless Steel Construction — Resists oxidation, moisture, and mild chemical exposure, extending service life in humid or outdoor-adjacent environments.
  • 🔄Consistent Elastic Return — Uniform coil winding maintains predictable spring rate across the full compression stroke, reducing assembly variability.
  • 📦Flexible Quantity Packs — Available in quantities from 1 to 150 pieces so you can order exactly what your project or stock requires without over-buying.
  • 🔧Broad Application Range — Suitable for electronics, mechanical devices, light automation fixtures, hobby robotics, and general DIY spring replacement tasks.

❓ Frequently Asked Questions

How do I choose the right free length for my application?

Measure the distance between your spring seats when the mechanism is at rest (uncompressed). Select a free length that is longer than this distance by the amount of travel you need. For example, if your seat gap is 20mm and you need 10mm of compression travel, choose a spring with a free length of at least 30mm. All available lengths are listed in the SIZE variant selector above.

What is the inner diameter, and what guide rod size fits inside?

With a 6mm outer diameter and 1mm wire diameter, the inner diameter is approximately 4mm. A guide rod up to ~3.5mm in diameter will fit inside with clearance. For bore-guided applications, the bore should be at least 6.2mm to allow the spring to compress freely without side friction.

Is 304 stainless steel suitable for outdoor or humid environments?

Yes. 304 stainless steel offers good resistance to atmospheric corrosion, moisture, and mild chemical exposure. It is a solid choice for indoor humid environments, light outdoor use, and applications where carbon steel springs would rust. For highly corrosive or marine environments, 316 stainless steel would provide superior protection.

Can these springs be used in electrical or electronic assemblies?

Yes. 304 stainless steel is non-magnetic (austenitic) and has moderate electrical conductivity. These springs are commonly used in battery contacts, push-button return mechanisms, and connector assemblies. Verify the current rating requirements of your circuit before using any spring as an electrical conductor.

How do I compare spring strength across different lengths?

For springs with the same wire diameter and outer diameter, a shorter free length generally produces a stiffer spring (higher spring rate) while a longer free length produces a softer spring. If you need a specific load at a specific deflection, please contact us with your load and travel requirements and we can help you identify the best length option.

What quantity should I order for a prototype vs. production run?

For prototyping and testing, ordering 2–10 pieces lets you validate fit and spring rate before committing to larger quantities. For small production runs or workshop stock, packs of 20–100 pieces offer a cost-effective buffer. Quantities from 1 to 150 pieces are available per order — select your preferred quantity in the QTY variant above.

Are these springs suitable for high-temperature applications?

304 stainless steel retains good mechanical properties up to approximately 300°C (572°F) for intermittent use. For continuous high-temperature service above this range, a high-temperature alloy spring would be more appropriate. For most DIY, electronics, and light mechanical applications operating at ambient temperatures, these springs perform reliably.
