Compression Springs Wire Dia 0.6mm OD 8mm — Reliable Vibration Damping for Precision Applications
Engineers, hobbyists, and small-batch manufacturers who need consistent spring force in compact assemblies often struggle to find springs that hold their load rating without corroding or fatiguing prematurely. These 304 stainless steel compression springs deliver repeatable elastic performance in environments where carbon steel would rust or weaken over time.
Each spring is formed from 304-grade stainless steel wire with a cross-section (CS) of 0.6 mm and an outer diameter (OD) of 8 mm (approximately 0.315 in). Free lengths span from 10 mm (0.39 in) to 305 mm (12.0 in) across the available size options, giving you precise control over travel and spring rate for your specific assembly.
Typical use cases include vibration-damping mounts in electronic enclosures, return-force mechanisms in jigs and fixtures, tension-relief components in robotics and automation builds, and replacement springs for small appliances or precision instruments requiring a 0.6 mm wire diameter compression spring.

Compatibility: Suitable for spring seats or bores accepting an OD of 8 mm. Verify free length and spring rate against your load requirements before ordering. Select your size and quantity from the variant options above.
✅ Key Features of These Compression Springs
🔩
304 Stainless Steel Construction — Resists oxidation, mild acids, and humidity, making these springs suitable for both indoor and outdoor assemblies where corrosion is a concern.
📐
Precise Wire Diameter 0.6 mm — Consistent cross-section across the full production run ensures repeatable spring rate and load deflection characteristics from piece to piece.
🔄
Outer Diameter 8 mm — Compact OD fits standard 8 mm spring pockets and guide rods, simplifying drop-in replacement or new-design integration.
📏
Wide Length Range (10–305 mm) — From ultra-short 10 mm (0.39 in) to full-length 305 mm (12.0 in / ~1 ft), covering a broad spectrum of travel and preload requirements in a single product family.
🛡️
Vibration Damping Performance — Closed and ground ends (typical for this spring class) provide stable seating and reduce lateral movement, contributing to effective vibration isolation in mounted assemblies.
📦
Flexible Pack Quantities — Available from 1 pc up to 200 pcs per order, supporting prototyping, small-batch production, and maintenance stock without over-ordering.

❓ Frequently Asked Questions
How do I choose the right free length for my application?
Measure the distance between your spring seats when the assembly is at rest (free position). Select a free length that is longer than this distance by the amount of preload travel you need. For vibration-damping applications, a preload of 10–20% of the free length is a common starting point. Use the SIZE(CSxODxL) variant selector to pick your exact length.
What load can a 0.6 mm wire diameter, OD 8 mm compression spring handle?
Load capacity depends on the free length and number of active coils, which vary by size option. Shorter springs with fewer coils are stiffer; longer springs are softer. For precise load and deflection data for a specific length, contact us to confirm the spring rate before ordering for load-critical applications.
Are these springs corrosion-resistant for outdoor or humid environments?
Yes. 304 stainless steel provides good resistance to atmospheric corrosion, moisture, and mild chemical exposure. It is not recommended for prolonged immersion in chloride-rich solutions (e.g., seawater) without additional protection. For marine-grade applications, 316 stainless steel would be a stronger choice.
Will an OD 8 mm spring fit my existing spring pocket or guide rod?
The outer diameter is 8 mm (0.315 in) and the inner diameter is approximately 6.8 mm (0.268 in). For a guide rod, the rod diameter should be slightly smaller than 6.8 mm to allow free movement. For a spring pocket, the bore should be slightly larger than 8 mm. Always verify clearances in your design before bulk ordering.
Can I use these springs for vibration isolation in electronic or mechanical assemblies?
Yes. The closed-end construction provides stable seating and reduces lateral rocking, which is beneficial for vibration-damping mounts. Select a free length that gives adequate preload under the expected static load, and ensure the spring rate is low enough to isolate the vibration frequency of your source.
How do I decide between ordering 10 pcs vs. 100 pcs or more?
For prototyping or testing a new design, start with 10–20 pcs to validate fit and performance before committing to larger quantities. For production runs or maintenance stock, ordering 50–200 pcs typically reduces the per-unit cost significantly. Use the QTY(pcs) variant selector to compare pricing across pack sizes before adding to cart.
What is the difference between the 10 mm and 305 mm length options?
The 10 mm free length is suited for very compact assemblies with minimal travel, such as small switch mechanisms or micro-fixtures. The 305 mm (approximately 12 inches) free length is designed for applications requiring long travel or high preload, such as industrial dampers or long-stroke return mechanisms. All lengths share the same 0.6 mm wire diameter and 8 mm OD.
