Finding the right compression spring for a repair or build project shouldn't mean ordering a custom batch and waiting weeks. Whether you're a mechanical engineer prototyping a new assembly, a hobbyist restoring vintage equipment, or a maintenance technician replacing worn-out coil springs on the spot, having the exact wire diameter, outer diameter, and free length in stock is what separates a smooth workflow from a frustrating delay. These 2mm wire diameter stainless steel compression springs are stocked across a wide matrix of sizes so you can match your spec precisely and get back to work.
Each spring is wound from 2mm (0.079 in) stainless steel wire. Outer diameters span 10mm–35mm (approx. 0.39–1.38 in) and free lengths range from 10mm–100mm (approx. 0.39–3.94 in). The closed-end, ground design provides a flat seating surface for consistent load distribution. Sold in packs of 1, 2, 4, or 10 pieces depending on the size selected — see variant options for exact pack quantities.
Typical applications include: replacing compression springs in automotive suspension jigs and test fixtures; sourcing small-batch coil springs for 3D-printer extruder assemblies and CNC machine tool holders; and supplying maintenance kits for industrial valve actuators, pneumatic cylinders, and door-latch mechanisms where a 2mm wire diameter stainless compression spring is specified.
Consistent 2mm (0.079 in) wire cross-section across all variants for predictable spring rate and load capacity.
Outer diameters from 10mm to 35mm and free lengths from 10mm to 100mm — choose the exact combination from the variant selector.
Wound from stainless steel wire for corrosion resistance in humid, wet, or mildly chemical environments where carbon steel would rust.
Flat ground ends ensure square seating against mating surfaces, reducing lateral deflection and improving load uniformity.
Available in packs of 1, 2, 4, or 10 pieces depending on size — ideal for prototyping (small packs) or maintenance stock (10-piece packs).
Standard metric dimensions make these springs straightforward drop-in replacements for worn coil springs in machinery, fixtures, and consumer products.

Measure the bore or housing your spring sits in — the spring's outer diameter should be slightly smaller than the bore (typically 0.5–1mm clearance). For free length, measure the uncompressed gap the spring must fill, then add the required travel (compression distance). Use the variant selector to pick the OD and length combination that matches your measurements.
Spring rate varies by outer diameter and free length combination. Because this product covers a wide matrix of sizes, the rate for each specific variant differs. If you need an exact spring rate value for engineering calculations, please contact us with your chosen OD and length and we will provide the specification.
Yes. These springs are wound from stainless steel wire, which offers significantly better corrosion resistance than carbon steel or zinc-plated springs. They are suitable for humid, wet, and mildly corrosive environments. For highly aggressive chemical environments (e.g., salt spray, strong acids), contact us to confirm the exact stainless grade before ordering.
These 2mm wire diameter coil springs are used in a wide range of applications: mechanical assemblies, 3D printer extruders, CNC tool holders, valve actuators, pneumatic cylinders, door latches, electronic enclosure clips, hobby robotics, and general DIY repair projects. The stainless construction makes them especially suitable where rust is a concern.
Pack quantity depends on the size variant selected. Smaller or longer springs (typically 60mm and above) are sold in packs of 1 or 2 pieces. Mid-range lengths (15mm–50mm) are generally sold in packs of 10 pieces. The shortest lengths may be available in 4-piece packs. The exact quantity is shown in the variant name (e.g., "15mm & 10pcs" means 10 pieces at 15mm free length).
In most cases, yes. Measure your existing spring's wire diameter (should be 2mm), outer diameter, and free length, then select the matching variant. If your original spring has a specific spring rate requirement, contact us to verify the rate matches before ordering to ensure proper function.
Yes. HomeDIYer stocks compression springs in multiple wire diameters and outer diameter ranges. Browse our full spring collection or use the search bar to find the wire diameter you need. If you require a specific material (e.g., music wire, chrome silicon, or a different stainless grade), contact us and we will advise on availability.
