1.6mm Wire Compression Spring — A2 Stainless Steel, Consistent Force Across Every Application

Engineers, makers, and maintenance professionals who rely on precise spring force know the frustration of springs that corrode, fatigue prematurely, or arrive with inconsistent free length. These 1.6mm wire diameter compression springs are manufactured from A2 (304) stainless steel to deliver repeatable load characteristics and long service life in demanding environments.

Each spring features a wire diameter of 1.6mm (0.063 in) and an outer diameter ranging from 10mm to 15mm (0.39–0.59 in), with free lengths spanning 10mm to 200mm (0.39–7.87 in). The body is formed from A2 stainless steel wire with closed and ground ends for stable seating and accurate load measurement.

Typical use cases include robotics actuator return mechanisms requiring a 1.6mm wire compression spring with consistent spring rate, DIY jig and fixture clamping assemblies needing a stainless steel compression spring 10-15mm OD, and light industrial valve or switch assemblies where a corrosion-resistant compression spring 200mm length is required.

⚙️ Compatibility: Suitable for spring guides or bores sized to match the selected outer diameter. Verify free length, outer diameter, and wire diameter against your application before ordering. Available in packs of 1, 5, or 10 pieces.

✅ Key Features of These 1.6mm Wire Compression Springs

🔩 A2 Stainless Steel Construction

Formed from A2 (304) stainless steel wire for reliable corrosion resistance in humid, wet, and mildly acidic environments.

📐 Precise 1.6mm Wire Diameter

Consistent 1.6mm wire cross-section ensures repeatable spring rate and load deflection across the full range of outer diameters and lengths.

📏 Wide Size Range — 10mm to 200mm Free Length

Outer diameters from 10–15mm and free lengths from 10–200mm cover a broad spectrum of design requirements in a single product family.

🏁 Closed and Ground Ends

Ground end coils provide a flat, stable seating surface that reduces lateral deflection and improves load accuracy in guided assemblies.

📦 Flexible Pack Quantities

Order as a single piece for prototyping, a 5-pack for small batch builds, or a 10-pack for production runs — all from the same variant selector.

🔄 Broad Application Compatibility

Suited for robotics, automation, jigs, fixtures, valves, switches, and general mechanical assemblies requiring a compact stainless compression spring.

❓ Frequently Asked Questions

How do I choose the right outer diameter and length for my application?

Measure the bore or guide rod your spring will seat in. The outer diameter of the spring should be slightly smaller than the bore (typically 0.5–1mm clearance) or slightly larger than the guide rod. For free length, select a spring that is longer than your required compressed length to ensure adequate working travel and preload.

What is the spring rate of these 1.6mm wire compression springs?

Spring rate varies by outer diameter and free length combination. Longer springs with larger outer diameters will generally have a lower spring rate. If you need a specific spring rate value for your design, please contact us with your selected variant dimensions and we will provide the calculated rate.

Are these springs corrosion-resistant enough for outdoor or wet environments?

Yes. A2 (304) stainless steel provides good resistance to atmospheric corrosion, fresh water, and mild chemical exposure. For highly aggressive environments such as saltwater immersion or strong acids, A4 (316) stainless steel would be more appropriate. For typical outdoor, humid, or lightly wet applications, A2 is a reliable choice.

What does "closed and ground ends" mean, and why does it matter?

Closed ends means the final coils are wound tightly against the adjacent coil with no gap, creating a solid end. Ground ends means those closed coils are then machined flat. This flat seating surface ensures the spring sits squarely on its seat or guide, reducing lateral (side) deflection and improving load measurement accuracy — important for precision assemblies.

Can I use these springs in robotics or automation equipment?

Yes. The consistent wire diameter, closed and ground ends, and stainless steel construction make these springs well-suited for robotics actuator return mechanisms, gripper assemblies, and light automation fixtures. Verify the spring rate and maximum deflection against your actuator travel requirements before finalising your design.

What is the difference between the 1-piece, 5-piece, and 10-piece pack options?

All three pack options contain identical springs of the same specification. The 1-piece pack is ideal for prototyping or replacement of a single spring. The 5-piece pack suits small batch builds or keeping spares on hand. The 10-piece pack offers the best per-unit value for production runs or larger assemblies requiring multiple springs of the same size.

How do I verify the spring will fit my existing assembly?

Check three dimensions against your assembly: (1) outer diameter — must clear the bore or housing; (2) wire diameter — affects the inner diameter and coil count; (3) free length — must be longer than your maximum compressed length. If you are replacing an existing spring, measure the original spring's wire diameter, outer diameter, and free length and match them to the variant selector above.
