Compression Spring 1.4mm Wire — Reliable Spring Steel Coil for Demanding DIY & Industrial Applications

When a worn-out or undersized spring causes your mechanism to fail mid-project, finding the right replacement fast matters. These compression springs are designed for makers, engineers, and workshop professionals who need consistent, repeatable force across a wide range of assemblies — from custom jigs and fixtures to production machinery and consumer product repairs.

Each spring is formed from spring steel wire with a nominal wire diameter of 1.4mm (approximately 0.055 in). The outer diameter (OD) ranges from 8mm to 22mm (approx. 0.31–0.87 in), and free lengths span 10mm to 50mm (approx. 0.39–1.97 in) depending on the variant selected. The open-coil, cylindrical body provides linear compression force with flat, ground-style ends for stable seating.

These compression springs suit a broad range of use cases: replacing valve return springs in pneumatic and hydraulic assemblies, providing preload in precision jigs and clamping fixtures, and acting as buffer elements in consumer electronics enclosures and mechanical keyboards. Their consistent wire gauge also makes them a reliable choice for batch-production prototyping where spring-rate repeatability is critical.

🔧 Compatibility: Suitable for standard spring pockets and bores sized to match the selected OD variant. Verify free length and OD against your housing dimensions before ordering. Available in 10 PCS or 100 PCS quantities.

✅ Key Features of These Compression Springs

🔩
1.4mm Spring Steel Wire

Consistent wire diameter across all variants ensures predictable spring rate and reliable force output in repetitive-cycle applications.

📐
Wide OD & Length Range

OD from 8mm to 22mm and free lengths from 10mm to 50mm give you the flexibility to match a broad variety of spring pockets and bore sizes.

⚙️
Open-Coil Cylindrical Design

The open-coil geometry allows for smooth, linear deflection with minimal lateral buckling, suitable for guided and unguided spring applications.

🛡️
Spring Steel Construction

Spring steel offers a strong balance of tensile strength and elastic recovery, maintaining set resistance through repeated compression cycles.

📦
Flexible Pack Quantities

Order in 10 PCS for prototyping and repair, or 100 PCS for production runs and workshop stock — both options available for every size variant.

🔄
Consistent Coil Pitch

Uniform coil pitch throughout the body ensures even load distribution and reduces stress concentration during compression.

❓ Frequently Asked Questions

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

Measure the bore or spring pocket your spring will sit in. The spring OD should be slightly smaller than the bore diameter to allow free movement without binding. For free length, select a spring that is longer than your required compressed length to ensure adequate preload and travel. Use the Size variant selector to match wire diameter (1.4mm), OD, and free length to your housing dimensions.

What is the spring rate of these compression springs?

Spring rate depends on the specific OD and free length combination selected. Longer springs with larger ODs will generally have a lower spring rate, while shorter springs with smaller ODs will be stiffer. If you require a specific spring rate value, please contact us to confirm before ordering.

Are these springs corrosion resistant?

These springs are made from spring steel, which offers good mechanical properties but has limited inherent corrosion resistance compared to stainless steel. For outdoor, humid, or chemically exposed environments, consider applying a protective coating or lubricant after installation. For applications requiring stainless steel springs, please contact us to confirm availability.

Can these springs be used in high-temperature environments?

Spring steel compression springs are generally suitable for temperatures up to approximately 120–150°C (248–302°F) before significant loss of spring properties occurs. For elevated-temperature applications beyond this range, a high-temperature alloy spring may be more appropriate. Contact us to confirm suitability for your specific operating conditions.

What is the difference between the 10 PCS and 100 PCS options?

Both quantity options contain identical springs of the same size and specification. The 10 PCS pack is suited for prototyping, repair, or low-volume use, while the 100 PCS pack offers a lower per-unit cost for production runs, workshop stocking, or bulk replacement projects. Select your preferred quantity using the Quantitys variant selector.

How do I verify the spring fits my existing assembly before ordering?

Before ordering, measure the wire diameter, outer diameter, and free length of your existing spring using calipers. Match these measurements to the Size variant options listed (format: Wire Diameter × OD × Free Length). If your existing spring falls between listed sizes, select the closest match and verify the compressed length and load requirements are still met. Contact us if you need help selecting the correct variant.

Are these springs suitable for use in compression jigs and fixtures?

Yes. The consistent wire diameter and open-coil cylindrical design make these springs well-suited for use in compression jigs, clamping fixtures, and tooling applications where repeatable preload force is required. Select the OD and length combination that matches your fixture's spring pocket dimensions.
