Wire Dia 1.6mm 1.8mm 2.0mm 304 Stainless Steel Compression Springs L=60mm-100mm

Wire diameter directly affects the spring rate (stiffness). A 1.6mm wire produces a lighter, more flexible spring suitable for low-load applications like latches or light return mechanisms. A 2.0mm wire yields a stiffer spring better suited for higher-load assemblies. If you know your required load and deflection, use a spring rate calculator with the OD and free length to confirm the right wire gauge.

The spring OD should be 0.5mm–1mm smaller than your bore or housing inner diameter to allow free travel without binding. For example, if your housing ID is 16mm, select a spring with a 15mm OD. Always measure your housing before ordering.

Yes. 304 stainless steel offers solid resistance to rust and oxidation in most outdoor, humid, and mildly corrosive environments. It is not recommended for prolonged exposure to chloride-rich environments (e.g., saltwater immersion), where 316 stainless would be more appropriate.

Free length is the spring's natural, unloaded length (60mm–100mm in this range). Compressed length (solid height) is the minimum length when fully compressed coil-to-coil. Always ensure your assembly has enough clearance to accommodate the solid height, and that the free length fits within your housing when unloaded.

Yes. These compression springs are well-suited for DIY robotics, actuator return mechanisms, and light automation assemblies. Select the wire diameter and OD that match your required spring force and housing geometry. For precision applications, verify the spring rate against your load requirements.

Measure the available cavity depth in your assembly when the spring is at rest (unloaded). The spring's free length should fit within this space with some clearance. Also confirm the compressed length (solid height) does not exceed the minimum gap in your assembly when fully loaded. If unsure, contact us to confirm before ordering.

These springs feature closed ends, which provide a flat seating surface for stable positioning in spring pockets and reduce lateral deflection under axial load. This makes them suitable for most standard compression spring applications.
