Compression Springs with 0.8mm Wire Diameter — Reliable Elastic Force for Precision DIY Applications

When your project demands consistent, repeatable spring force in a compact form factor, undersized or mismatched springs cause binding, premature fatigue, and failed assemblies. Makers, electronics hobbyists, and small-workshop engineers who need dependable small-diameter compression springs will find this range purpose-built for tight-tolerance work.

These compression springs are wound from carbon steel wire with a diameter of 0.8mm (0.031 in). Outer diameters span 5mm to 14mm (approx. 0.20 in to 0.55 in), and free lengths range from 5mm to 50mm (approx. 0.20 in to 1.97 in). Each order ships in a pack of 10 or 50 pieces, letting you stock the exact quantity your build requires.

Typical use cases include small compression spring for electronics enclosures and PCB retention clips, miniature pressure spring for pen mechanisms and push-button assemblies, and light-load return spring for 3D-printer extruder arms and CNC limit-switch actuators.

⚙️ Compatible with standard spring seats and bores sized for 5mm–14mm OD. Verify bore clearance and seat depth before ordering.

✅ Key Features of These Compression Springs

🔩 0.8mm Carbon Steel Wire — Consistent wire gauge across the full OD range ensures predictable spring rate and reliable elastic return under repeated cycling.
📏 Wide OD Selection (5–14mm) — Ten outer-diameter options from 5mm to 14mm let you match the spring precisely to your bore or seat without custom fabrication.
📐 Multiple Free Lengths (5–50mm) — Choose from 5mm to 50mm free lengths in 5mm increments to dial in the travel and preload your assembly needs.
📦 10 or 50 Piece Packs — Order a trial pack of 10 for prototyping or a bulk pack of 50 for production runs and repair stock, reducing per-unit cost.
🛡️ Closed & Ground Ends — Flat, closed ends provide stable seating on flat surfaces and reduce lateral deflection during compression, extending service life.
⚡ Broad Application Range — Suited for push-button returns, pen clips, battery contacts, sensor actuators, and light-load mechanical assemblies across hobby and workshop environments.

❓ Frequently Asked Questions

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

Measure the bore or seat your spring will sit in. The spring OD should be 0.5mm–1mm smaller than the bore ID to allow free movement without binding. For a shaft-guided spring, the spring ID (OD minus twice the wire diameter) should be at least 0.5mm larger than the shaft diameter.

What free length should I select?

Free length is the uncompressed length of the spring. Choose a free length that gives you the desired preload and travel within your assembly. As a rule of thumb, avoid compressing a spring beyond 80% of its free length to prevent coil bind and premature fatigue.

Are these springs corrosion-resistant?

These springs are made from carbon steel with a bright (uncoated) finish, which offers moderate corrosion resistance suitable for indoor and dry environments. For humid, wet, or outdoor applications, consider applying a light coat of oil or using stainless steel springs instead.

What is the spring rate (stiffness) of these compression springs?

Spring rate varies by OD and free length combination. Shorter springs with larger wire-to-OD ratios will be stiffer. Exact spring rate values are listed in the variant details. If you need a specific rate for an engineering application, please contact us to confirm before ordering.

Are these compatible with standard spring seats and plungers?

Yes. The closed and ground ends provide flat, stable contact with standard flat spring seats. Verify that your seat or plunger bore accommodates the selected OD with at least 0.5mm clearance. These springs are not pre-loaded and can be used in both compression and light-preload configurations.

Should I order the 10-piece or 50-piece pack?

The 10-piece pack is ideal for prototyping, testing fit, or low-volume repairs where you need just enough to validate your design. The 50-piece pack offers a lower per-unit cost and is suited for production runs, workshop stock, or projects requiring multiple spring sizes across a build.

Can these springs be used in electronic devices such as battery contacts or push buttons?

Yes. The small wire diameter (0.8mm) and compact OD range (5–14mm) make these springs well-suited for battery contact springs, push-button return mechanisms, and PCB retention clips. Ensure the spring's compressed length does not exceed the available travel in your device housing.
