Compression Springs 304 Stainless Steel Wire Dia 0.8mm Pressure Length 5mm-305mm

Match the spring outer diameter (OD) to your bore or housing ID, leaving a small clearance (typically 0.5–1 mm). Then select a free length that gives you the desired compressed length plus the required travel. Finally, verify the spring rate meets your load requirement. If you are unsure, start with a mid-range length and test before committing to a larger quantity.

A 0.8 mm wire diameter spring is designed for light-duty applications. Exact load capacity depends on the spring OD and free length of the specific variant. Shorter springs with smaller ODs will have higher spring rates; longer springs with larger ODs will be softer. Contact us if you need spring rate data for a specific size.

Yes. 304 stainless steel offers good resistance to atmospheric corrosion, moisture, and mild chemicals. It is suitable for most outdoor DIY and light industrial environments. For highly aggressive environments (saltwater immersion, strong acids), consider 316 stainless steel instead.

Many makers use small-diameter compression springs in 3D printer bed-leveling mounts and extruder mechanisms. Select a spring OD that fits your existing spring seat and a free length that provides the correct preload. The 0.8 mm wire diameter variants in the 5–10 mm OD range are commonly used for these applications.

Yes. The uncoated 304 stainless steel surface is electrically conductive and corrosion-resistant, making these springs suitable for spring-loaded contacts, battery terminals, and PCB test fixtures. Verify the contact resistance meets your circuit requirements before use in precision electronics.

The 1 Pcs option is ideal for one-off repairs or prototyping where you only need a single spring. The 10 Pcs pack offers a lower per-unit cost and is better suited for production runs, workshop stock, or projects requiring multiple springs of the same size.

Measure the wire diameter with calipers, then measure the outer diameter of the coil body. Finally, measure the free (uncompressed) length. Use these three dimensions — wire dia × spring OD × free length — to select the matching variant from the dropdown above.
