Spring Steel Pressure Return Spring Assortment 0.3/0.4mm Wire Dia 5-20mm Length for Hobbyist Craft Making Projects

### Product Highlights 1. Superior Corrosion Resistance: Crafted from high-quality 304 stainless steel, this compression spring effectively resists oxidation, water erosion and mild chemical corrosion even in humid, outdoor or corrosive working environments. It boasts 3 times longer service life than regular carbon steel springs, cutting down extra costs from frequent replacement. 2. Stable Long-Lasting Elasticity: Made of durable 304 stainless steel, it maintains consistent tension and original shape after more than 10,000 repeated compression cycles without deformation or elasticity loss, ensuring stable and reliable operation of connected devices. 3. Burr-Free Smooth Surface: Processed with high-precision edge polishing technology, it has no sharp burrs or uneven spots on the surface, which reduces friction with matching assembly parts, avoids scratches on connected components and lowers wear during long-term operation. 4. Multiple Size Adaptability: We offer a wide range of wire diameters, outer diameters and length specifications to fit different load bearing requirements and installation space limits, perfectly meeting the needs of industrial machinery, furniture hardware, toy production, automobile maintenance and personal DIY projects.
