A2 Stainless Steel Compression Springs — Precise Load Control, Wire Dia 2mm

Engineers, makers, and maintenance professionals who rely on consistent spring force know the frustration of springs that corrode, fatigue, or lose tension under load. These A2 stainless steel compression springs with a 2mm wire diameter are engineered for applications where dimensional accuracy and corrosion resistance are non-negotiable — from industrial machinery to precision DIY assemblies.

Each spring is manufactured from A2 (304) stainless steel wire with a nominal diameter of 2mm (0.079 in). The outer diameter spans 10mm to 20mm (approx. 0.39 in to 0.79 in), and free lengths range from 10mm to 120mm (approx. 0.39 in to 4.72 in). Springs are supplied in packs of 1, 2, 4, 5, or 10 pieces depending on the selected variant.

Typical use cases include compression spring replacement in mechanical assemblies, return-force mechanisms in robotics and automation, valve and actuator spring applications, and small-batch prototyping where consistent spring rate and corrosion resistance are required.

⚙️ Compatible with standard spring seats and housings sized for 2mm wire diameter. Verify free length and outer diameter against your application before ordering.

✅ Key Features of These A2 Stainless Steel Compression Springs

🔩 A2 (304) Stainless Steel — Inherent corrosion resistance suitable for humid, wet, and mildly chemical environments without surface treatment.
📐 Wire Diameter 2mm — Consistent wire cross-section across all variants ensures predictable spring rate and load-deflection behaviour.
🔄 Wide Size Range — Outer diameters from 10mm to 20mm and free lengths from 10mm to 120mm cover a broad spectrum of mechanical design requirements.
📦 Flexible Pack Quantities — Available in packs of 1, 2, 4, 5, or 10 pieces so you can order exactly what your project demands without excess stock.
⚖️ Consistent Spring Rate — Cold-wound construction maintains uniform pitch and coil geometry for repeatable force output across the compression stroke.
🛠️ Broad Application Fit — Suitable for return mechanisms, clamping fixtures, valve springs, robotics, and general mechanical assemblies requiring a compact compression element.

❓ Frequently Asked Questions

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

Measure the bore or housing your spring sits in and subtract a small clearance (typically 0.5–1mm) to get your target OD. For free length, measure the uncompressed gap your spring must fill, then add the required travel distance. Select the variant whose OD and free length best match those values.

What load can a 2mm wire diameter compression spring handle?

Load capacity depends on OD, free length, and number of active coils — not wire diameter alone. A 2mm wire spring with a smaller OD and shorter free length will typically have a higher spring rate than a longer, larger-OD spring of the same wire size. If you need a specific load rating, contact us with your deflection and force requirements.

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

A2 (304) stainless steel offers good resistance to atmospheric corrosion, fresh water, and mild chemical exposure. It is not recommended for prolonged immersion in salt water or strong acids. For marine or highly corrosive environments, A4 (316) stainless steel springs would be more appropriate.

Can I use these springs in food-contact or medical applications?

A2 stainless steel is widely used in food-processing equipment. However, compliance with specific food-contact or medical-device regulations depends on your jurisdiction and application. Please verify material certifications with your regulatory body before use in regulated environments.

What is the difference between the pack sizes — should I buy 1, 2, 4, 5, or 10 pieces?

Pack size affects unit cost and is designed to match common project needs. Single pieces suit one-off repairs or prototyping. Packs of 4 or 10 are cost-effective for small production runs or when you need spares on hand. Select the pack that matches your quantity requirement to avoid unnecessary stock.

How do I verify the spring fits before I commit to a larger order?

Order a single piece or the smallest available pack for your target size first. Check the OD against your housing, confirm the free length suits your assembly, and test the spring rate under your expected load. Once verified, you can order larger quantities with confidence.

Are the ends of these springs closed and ground, or open?

End configuration varies by size. Smaller, shorter springs in this range typically feature closed (but not ground) ends. If your application requires flat, ground ends for precise seating, please contact us to confirm the end style for your specific variant before ordering.
