These stainless steel compression springs are designed for makers, engineers, and DIY enthusiasts who need a dependable elastic component that holds up over repeated cycles without degrading.\u003c\/p\u003e\n    \u003cp\u003eEach spring is formed from 1.0mm wire diameter stainless steel, with outer diameters of either 12mm (~0.47 in) or 13mm (~0.51 in), and lengths ranging from 15mm to 305mm (~0.59 in to ~12.0 in). The coil geometry provides a consistent spring rate across the full compression range, and the stainless steel construction resists oxidation in both indoor and light outdoor environments.\u003c\/p\u003e\n    \u003cp\u003eThese compression springs suit a wide range of applications: use them as small coil springs in mechanical assemblies, replacement springs in tool mechanisms, tension-return components in jigs and fixtures, or as precision elastic elements in robotics and automation projects. Whether you need a short 15mm spring for a compact latch or a 305mm spring for a longer-travel mechanism, this range covers the most common DIY and light-industrial spring sizes.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"hdiy-compat\"\u003e\n    \u003cspan class=\"hdiy-compat-icon\"\u003e🔩\u003c\/span\u003e\n    Compatible with standard spring seats, guide rods, and bores sized for 12mm or 13mm OD springs.
