Compression Spring 1.4mm Wire — Reliable Coil Spring for DIY and Mechanical Applications

When a project demands consistent return force and dimensional accuracy, undersized or mismatched springs cause failures that are frustrating to diagnose. Engineers, makers, and repair technicians who work with small mechanical assemblies need compression springs that hold their rated dimensions across repeated cycles without taking a permanent set.

These compression springs are wound from spring steel wire with a nominal diameter of 1.4mm (approximately 0.055 in). The outer diameter spans from 8mm to 22mm (roughly 0.31 in to 0.87 in), and free lengths range from 10mm to 50mm (approximately 0.39 in to 1.97 in). Each spring features closed and ground ends for stable seating and consistent load distribution.

Typical use cases include robotics actuator return mechanisms, small appliance pressure valves, DIY jig and fixture clamping systems, and precision instrument assemblies where a compact 1.4mm wire compression spring with controlled OD is required.

🔧 Compatible with standard spring seats, plunger housings, and bore diameters matching the listed OD. Verify free length and OD against your assembly clearance before ordering.

✅ Key Features of These 1.4mm Wire Compression Springs

🌀Spring Steel Wire

Wound from spring steel with a 1.4mm wire diameter for consistent elastic return and fatigue resistance across repeated compression cycles.

📐Wide Size Range

OD from 8mm to 22mm and free lengths from 10mm to 50mm cover a broad range of small mechanical applications without custom tooling.

⚙️Closed and Ground Ends

Ground end coils provide a flat, stable seating surface that reduces lateral deflection and ensures even load transfer to mating components.

🔩Consistent Coil Pitch

Uniform coil spacing maintains predictable spring rate throughout the compression stroke, reducing variability in force-sensitive assemblies.

📦Bulk Pack Options

Available in 10-piece or 100-piece quantities to suit both prototyping runs and small-batch production needs.

🛠️Broad Application Fit

Suited for robotics, DIY fixtures, valve mechanisms, instrument assemblies, and general mechanical engineering projects requiring compact compression springs.

❓ Frequently Asked Questions

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

Measure the bore or housing diameter your spring must fit inside, then select an OD that provides 0.5–1mm clearance. For free length, choose a spring that is 20–30% longer than your required compressed length to stay within the elastic range and avoid coil bind.

What material are these springs made from?

These springs are wound from spring steel wire. Spring steel offers a good balance of tensile strength, elasticity, and fatigue life for general mechanical applications. If your environment involves exposure to moisture or chemicals, consider whether a coated or stainless variant is more appropriate for your use case.

Are these springs corrosion resistant?

Spring steel provides moderate corrosion resistance suitable for indoor and dry environments. For applications exposed to humidity, water, or corrosive media, additional protective measures such as a coating or use of stainless steel springs should be considered.

What does the size format (e.g., 1.4mm X 10mm X 20mm) mean?

The three dimensions represent: wire diameter × outer diameter × free length. For example, 1.4mm X 10mm X 20mm means a spring with 1.4mm wire, 10mm outer diameter, and 20mm free length. Always verify all three dimensions match your assembly requirements.

Can I use these springs in robotics or automation projects?

Yes. The compact wire diameter and range of OD and length options make these springs well-suited for return mechanisms, gripper assemblies, and actuator reset functions in robotics and small automation systems. Confirm the spring rate and travel match your load requirements.

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

Both options contain identical springs of the same size and specification. The 10-piece pack is suited for prototyping, repair, or low-volume builds. The 100-piece pack offers a lower per-unit cost for small-batch production or stocking purposes.

How do I verify the spring rate before purchasing?

Spring rate depends on wire diameter, OD, free length, and number of active coils. If you need a specific spring rate, contact us with your load and deflection requirements and we can help identify the closest matching variant or advise on custom options.
