When a mechanism fails because a tiny spring loses tension, the whole project stalls — whether you're a hobbyist repairing a precision instrument, a technician servicing industrial equipment, or a maker building a custom mechanism. These 1.4mm wire diameter stainless steel compression springs are engineered for exactly those demanding, small-scale applications where dimensional accuracy and reliable spring force are non-negotiable.
Each spring is formed from 1.4mm stainless steel wire with outer diameters ranging from 10mm to 25mm (approx. 0.39" to 0.98") and free lengths from 10mm to 200mm (approx. 0.39" to 7.87"). The stainless steel construction provides inherent corrosion resistance and maintains consistent spring characteristics across a wide temperature range. Available in 1-piece or 5-piece packs to suit both prototyping and small-batch production needs.
Ideal for use in electronic enclosures, valve assemblies, and precision tooling where a compact stainless steel compression spring for small mechanisms is required. Also well-suited as a replacement spring for DIY repair projects, RC models, and light industrial fixtures requiring a reliable small coil spring with consistent load characteristics.
Consistent 1.4mm wire gauge across all variants for predictable spring rate and load performance in compact assemblies.
OD from 10–25mm and free length from 10–200mm (0.39"–7.87") — one listing covers dozens of precise dimensional combinations.
Corrosion-resistant stainless steel wire resists rust and oxidation, suitable for humid, outdoor, or light chemical environments.
Closed (ground or plain) end coils provide stable seating and even load distribution on both contact surfaces.
Choose 1-piece for single repairs or 5-piece packs for prototyping and small production runs — priced accordingly.
Tightly controlled coil pitch and diameter tolerances ensure repeatable performance across replacement and multi-unit applications.

Measure the bore or housing inner diameter to determine the maximum OD, then measure the shaft (if any) to determine the minimum ID. The free length should be longer than your required working length to allow for compression. Select the variant whose OD and free length best match your assembly constraints.
The ID is approximately OD minus twice the wire diameter (ID ≈ OD − 2 × 1.4mm). For example, a 10mm OD spring has an approximate ID of 7.2mm. Exact values may vary slightly due to manufacturing tolerances — contact us to confirm if your application requires a precise fit.
Yes. Stainless steel provides good corrosion resistance against moisture, light salt spray, and mild chemical exposure. For highly corrosive or submerged environments, verify the specific stainless steel grade meets your requirements.
Stainless steel compression springs generally perform well up to approximately 250–300°C (480–570°F) depending on the alloy. For applications exceeding this range, a high-temperature alloy spring would be more appropriate. Contact us if you need grade confirmation.
Both options contain identical springs. The 5-piece pack offers a lower per-unit cost and is ideal for prototyping, having spares on hand, or small production runs. The 1-piece option suits single repairs or testing a specific size before committing to a larger quantity.
Spring rate depends on wire diameter, OD, and number of active coils. Because free length and coil count vary by variant, the spring rate differs per size. If you need a specific spring rate or load capacity, please contact us with your dimensional requirements and we can advise on the best match.
These are general-purpose compression springs. Compatibility with specific plunger assemblies depends on the housing bore diameter and required spring force. Match the OD to the housing bore and the free length to the plunger travel for best results.
