10pcs Wire Dia.1.2mm-1.5mm OD 8mm-26mm Small Springs Compression Spring Steel

Measure the bore or housing inner diameter to determine the maximum outer diameter (OD) your spring can fit. Then measure the shaft or guide rod to confirm the inner diameter clearance. Finally, measure the available free-length space and the compressed length you need. Match these to the Wire Diameter, OD, and Length options in the variant selector above.

These springs are made from steel wire. Steel compression springs offer a good balance of tensile strength and spring-back consistency for general mechanical, DIY, and repair applications. If your application requires corrosion resistance in wet or outdoor environments, consider whether a coated or stainless variant is needed.

Standard steel springs have limited corrosion resistance compared to stainless steel. For indoor, dry, or low-humidity environments they perform reliably. For outdoor, marine, or high-moisture applications, additional protection (such as a light oil coating) or a stainless steel alternative is recommended. Check the variant details or contact us to confirm surface treatment.

Wire diameter (WD) is the thickness of the steel wire used to coil the spring — it determines the spring's stiffness and load capacity. Outer diameter (OD) is the overall width of the coiled spring body — it determines whether the spring fits inside a bore or around a shaft. Both dimensions must be matched to your application for correct fitment and performance.

Yes. Small compression springs in the 8–26mm OD range are commonly used in push-button return mechanisms, door latches, pen clips, and similar light-duty applications. Select the OD and free length that match your housing dimensions. The 10-piece pack also gives you spares if you need to test multiple lengths during prototyping.

Spring rate and load capacity depend on wire diameter, OD, free length, number of active coils, and material. These specifications vary by variant and are not listed universally across all size combinations. If you need a specific spring rate for a load-critical application, please contact us with your wire diameter, OD, and free length selection so we can provide further technical details.

Compression springs in small sizes are often needed in multiples — for symmetrical mechanisms, parallel assemblies, or simply as replacements over time. A 10-piece pack reduces per-unit cost, ensures you have identical spares on hand, and avoids delays when a spring needs replacing mid-project.
