When a worn-out spring causes a mechanism to fail — whether it's a stuck valve, a sagging assembly, or a machine that won't return to position — finding the right replacement fast is critical. These compression springs are designed for hobbyists, maintenance technicians, and small-scale industrial users who need a dependable, ready-to-install solution across a wide range of applications.
Each spring is manufactured from carbon steel wire with a consistent helical coil structure. Outer diameters range from 22mm to 35mm (~0.87" to 1.38"), and free lengths span 10mm to 120mm (~0.39" to 4.72"). Wire diameter and spring rate vary by size — see variant options for exact specifications. Available in packs of 1, 4, 5, or 10 pieces to suit both single-repair and bulk workshop needs.
These compression springs are well-suited for mechanical return mechanisms in DIY furniture hardware, light industrial equipment maintenance, automotive jig fixtures, and maker/robotics projects requiring consistent axial force. Long-tail use cases include replacing compression springs in drawer slides, pneumatic valve assemblies, and custom spring-loaded clamps.
Outer diameters from 22mm to 35mm and free lengths from 10mm to 120mm cover a broad spectrum of replacement and custom-build needs.
Made from carbon steel wire, providing solid axial load resistance and consistent spring-back performance across repeated compression cycles.
Choose from 1, 4, 5, or 10-piece packs — ideal for single repairs, prototyping batches, or stocking your workshop spare parts bin.
Uniform pitch and closed ends ensure stable seating in spring pockets and predictable load-deflection behavior for engineering applications.
Applicable in drawer mechanisms, valve returns, jig fixtures, robotics, and light machinery — wherever a reliable axial restoring force is needed.
Standard metric sizing makes these springs straightforward substitutes for worn or broken OEM springs in common DIY and industrial equipment.

Match the outer diameter (OD) to your spring seat or bore — the spring OD should be slightly smaller than the bore ID. Then select a free length that gives you the desired compressed and extended travel. If replacing an existing spring, measure the OD, free length, and wire diameter of the original.
Load capacity depends on the specific OD, free length, and wire diameter of the variant selected. These springs are designed for light to medium-duty applications. For exact spring rate and maximum load data, refer to the variant specifications or contact us to confirm.
These springs are made from carbon steel, which offers good mechanical properties but limited corrosion resistance in wet or chemically aggressive environments. For outdoor or humid applications, consider applying a protective coating or using the springs in a sheltered assembly.
These are standard metric compression springs suitable for a wide range of DIY, mechanical, and light industrial uses. Always verify the OD, free length, wire diameter, and spring rate against your application's requirements before ordering. If you need help matching a spring to your project, contact us with your specifications.
All pack sizes contain identical springs — the difference is quantity only. A 1-piece pack is ideal for a single repair. Packs of 4, 5, or 10 are suited for workshop stock, prototyping, or projects requiring multiple springs of the same size.
Yes. The consistent coil geometry and standard metric sizing make these springs a practical choice for robotics, 3D-printed mechanisms, and custom maker builds that require reliable axial spring force. Select the OD and length that fits your spring pocket or guide rod.
Use calipers to measure: (1) Outer Diameter — across the widest point of the coil; (2) Free Length — the uncompressed total length; (3) Wire Diameter — the thickness of the wire itself. Match these three dimensions to the variant options listed above for the closest replacement.
