Compression Springs 1.6mm Wire Dia — Precise Load Control in 304 Stainless Steel

When a mechanism fails because a spring loses tension, corrodes, or fatigues prematurely, the entire assembly pays the price. Engineers, makers, and maintenance technicians who need a reliable, dimensionally consistent compression spring for light-to-medium load applications will find this series purpose-built for the task. These compression springs are designed for applications where corrosion resistance and repeatable spring force are non-negotiable.

Each spring is manufactured from 304 stainless steel wire with a diameter of 1.6mm (approximately 0.063 in). The outer diameter (OD) is available in 11mm (~0.433 in) and 12mm (~0.472 in), with free lengths spanning from 10mm (~0.394 in) up to 200mm (~7.874 in). The coil pitch and number of active coils vary by length variant — select your SIZE(CSxODxL) combination above to match your application envelope.

Typical use cases include DIY mechanical assemblies requiring consistent return force, robotics and automation jigs where corrosion-resistant springs reduce maintenance cycles, and small-batch manufacturing fixtures that demand dimensional repeatability across production runs. The stainless steel construction also suits outdoor or humid-environment installations where carbon steel springs would degrade.

⚙️ Compatibility: Suitable for spring seats, guide rods, or bores sized to accept OD 11mm or 12mm. Verify your housing bore and free-length clearance before ordering. Wire dia 1.6mm — confirm load requirements match your application.

✅ Key Features of These Compression Springs

🔩 304 Stainless Steel Construction

Resists oxidation, moisture, and mild chemical exposure — maintaining spring integrity in demanding environments without surface treatment.

📐 Precise Wire Diameter

Consistent 1.6mm wire diameter across all variants ensures predictable spring rate and load deflection behavior for engineering calculations.

📏 Wide Length Range

Free lengths from 10mm to 200mm (0.39–7.87 in) cover a broad spectrum of stroke and preload requirements in a single product family.

⭕ Two OD Options: 11mm & 12mm

Choose OD 11mm (~0.433 in) or OD 12mm (~0.472 in) to match your guide rod or bore diameter without custom tooling.

📦 Flexible Quantity Tiers

Order from 1 to 50 pieces per variant — ideal for prototyping single units or stocking spares for production maintenance.

🛡️ Corrosion-Resistant for Long Service Life

304 stainless alloy provides durability in humid, outdoor, and light-chemical environments where carbon steel springs would require frequent replacement.

❓ Frequently Asked Questions

How do I choose the right size for my application?

Select the SIZE(CSxODxL) variant that matches your housing bore (OD), required free length (L), and wire diameter (CS = 1.6mm). The OD must be smaller than your bore diameter, and the free length should exceed your required working length by your desired preload deflection. If you are unsure, measure your existing spring or consult your assembly drawing.

What is the load capacity of these springs?

Load capacity depends on the specific OD and free length combination selected. Shorter springs with the same wire diameter generally have a higher spring rate (stiffer), while longer springs are softer. For precise load and deflection data for your chosen variant, contact us to confirm — spring rate values vary by length and coil count.

Are these springs corrosion-resistant for outdoor or humid use?

Yes. 304 stainless steel offers good resistance to atmospheric corrosion, moisture, and mild chemical exposure. It is suitable for outdoor, humid, and light-industrial environments. For highly aggressive chemical or saltwater immersion environments, 316 stainless steel would be a stronger choice — please contact us if you need that grade.

Can I use these springs in robotics or automation fixtures?

Yes. The consistent wire diameter and dimensional tolerances make these springs well-suited for robotics jigs, automation fixtures, and small-batch manufacturing tooling where repeatable spring force is required. The stainless construction also reduces maintenance frequency in environments where carbon steel would corrode.

What is the difference between OD 11mm and OD 12mm variants?

The outer diameter determines which bore or guide rod the spring fits. OD 11mm (~0.433 in) suits smaller housings, while OD 12mm (~0.472 in) fits slightly larger bores. Both share the same 1.6mm wire diameter. Choose based on your housing inner diameter — the spring OD should be 0.5–1mm smaller than the bore for smooth operation.

How many pieces should I order for prototyping vs. production?

For prototyping or testing, the 1–3 piece tiers let you validate fit and load before committing to larger quantities. For production maintenance stock or small-batch manufacturing, the 10–50 piece tiers offer better per-unit value. Select your QTY(pcs) variant above to see the price for each quantity tier.

Are these open-end or closed-end compression springs?

These are open-end coil compression springs. If your application requires closed or ground ends for flat seating, please contact us to confirm end type availability for your specific size variant before ordering.
