Compression Spring 0.6mm Wire Dia 8-12mm Dia 10-305mm Length A2 Stainless Steel

Select based on three dimensions: wire diameter (0.6mm for all variants here), outer diameter (OD: 8–12mm), and free length (10–305mm). Match the OD to your bore or housing ID, and choose a free length roughly 20–30% longer than your required compressed length to stay within the elastic range.

A2 stainless steel (also known as 304 grade) contains approximately 18% chromium and 8% nickel, giving it strong resistance to oxidation and corrosion. For springs used in humid, outdoor, or lightly corrosive environments, A2 outperforms carbon steel by maintaining its mechanical properties without rusting.

Yes. A2 stainless steel provides good corrosion resistance for outdoor, humid, and light chemical exposure. For highly aggressive environments (saltwater immersion, strong acids), consider A4 (316) grade instead.

Absolutely. The 8–12mm OD range and 0.6mm wire diameter make these springs well-suited for 3D printer bed leveling, enclosure latches, and small actuator return mechanisms. Select the OD and length that match your specific mounting points.

For prototyping or single repairs, packs of 1, 5, or 10 are ideal. For production runs, small-batch manufacturing, or stocking a workshop, packs of 50, 100, or 200 offer better per-unit value. All pack sizes ship the same spring specification.

Free length is the spring's natural, unloaded length. When compressed, the spring shortens. As a general rule, avoid compressing a spring beyond 80% of its free length to prevent coil bind and permanent deformation. For example, a 50mm free-length spring should not be compressed below approximately 10mm.

Yes. All dimensions are specified in metric (mm). The OD range of 8–12mm aligns with common metric bore sizes and spring pockets used in standard mechanical assemblies, making them straightforward to integrate into metric-dimensioned designs.
