When a project demands consistent return force and long-term reliability, finding the right compression spring in the exact size you need can be a real challenge. Whether you're a hobbyist repairing a mechanism, a maker building a custom fixture, or a technician maintaining industrial equipment, these 1.6mm wire diameter stainless compression springs give you the precise fit without compromise.
Each spring is formed from 1.6mm (approximately 0.063 in) stainless steel wire, with outer diameters ranging from 10mm to 30mm (approx. 0.39–1.18 in) and free lengths from 10mm to 100mm (approx. 0.39–3.94 in). The closed-end coil construction provides stable seating on flat surfaces, and the stainless steel material delivers corrosion resistance suitable for both indoor and outdoor environments.
These coil springs are well-suited for a wide range of use cases: replacing worn-out compression springs in tool assemblies and jigs, providing return force in custom 3D-printed or CNC-machined enclosures, and serving as load-bearing elements in small mechanical devices, valves, latches, and spring-loaded fixtures. The broad size matrix — covering multiple outer diameters and lengths — makes it straightforward to find the right spring for your specific load and travel requirements.

Measure the bore or housing your spring will sit in — the outer diameter of the spring should be slightly smaller than the bore to allow free movement. For free length, choose a spring that is longer than your required compressed length to ensure adequate preload and travel. If you are unsure, select a size in the middle of the range and test before ordering in quantity.
Spring rate depends on the wire diameter, outer diameter, free length, and number of active coils. With a 1.6mm wire diameter, these springs are suited for light to moderate loads — typically applications requiring gentle return force rather than heavy-duty clamping. For specific spring rate values, please contact us with your selected variant dimensions.
Yes. These springs are made from stainless steel, which provides good resistance to rust and oxidation in humid, wet, or mildly corrosive environments. They are suitable for outdoor fixtures, marine-adjacent applications, and environments where standard carbon steel springs would corrode. For highly aggressive chemical environments, please confirm suitability before use.
Pack quantity varies by the outer diameter and length combination selected. Smaller, more common sizes are available in packs of 10, while larger or longer springs are offered in packs of 1, 2, or 5. The quantity is clearly shown in the "Length & Qty" variant option so you can select the pack size that matches your project needs.
Yes. The closed-end design and consistent outer diameter make these springs well-suited for spring pockets in 3D-printed parts, CNC fixtures, and custom enclosures. Ensure the spring pocket diameter is at least 0.5–1mm larger than the spring's outer diameter to allow free compression without binding.
Measure three key dimensions of your existing spring or housing: wire diameter, outer diameter, and free length. Match these to the variant options available. If you are replacing a worn spring, also note the number of coils if possible, as this affects the spring rate. Contact us if you need help matching a specific spring to your application.
Yes. The 1.6mm wire diameter and closed-end construction make these springs appropriate for light-duty valve return, latch mechanisms, and push-button assemblies. Select the outer diameter and length that matches your valve seat or latch housing dimensions for the best fit and consistent return force.
