Product: Compression spring — 12.0 mm (0.47 in) outer diameter • 1.2 mm (0.05 in) wire diameter • 40.0 mm (1.56 in) length Key benefits Precise fit: consistent 12 mm OD and 1.2 mm wire diameter make this spring suitable where tight dimensional tolerance is required. Durable performance: heattempered spring steel provides reliable elastic properties and improved fatigue life under repeated compression. Ready to handle: drytothetouch oil finish eases handling and installation while helping preserve the steel for longer service. What this spring does for you Provides controlled compression force in assemblies that require or dampening action. Maintains shape and performance over many cycles thanks to heat treatment. Simplifies replacement and work because dimensions and material are industrystandard for small mechanical and motorized applications. Material and finish Material: heattempered spring steel. Finish: drytothetouch oil finish for protection during storage and handling and for immediate use without messy residue. Compatibility and use Designed for applications that require a 12 mm OD, 1.2 mm wire diameter, and 40 mm length. Verify these dimensions against your assembly before ordering. Typical uses include home appliances, motor equipment and motors, and other compressedspring applications needing this size and strength. Practical use scenarios Appliance : worn compression springs in small household devices where the original parts share these dimensions. Motor assemblies: Use in motor equipment and actuator subassemblies that require a compact, heattempered compression spring. DIY and prototyping: Ideal for hobby projects or prototypes that call for a durable, readytoinstall compression spring with known dimensions and performance characteristics.
