Compression Spring A2 Stainless Steel 1.8mm Wire — Reliable Force Control for Makers & Engineers
When a project demands consistent return force without the worry of rust or fatigue failure, finding the right compression spring in the exact length you need can be a frustrating hunt. These A2 stainless steel compression springs with a 1.8 mm wire diameter and outer diameters of 22 mm, 24 mm, or 25 mm are designed for makers, workshop technicians, and mechanical engineers who need a dependable off-the-shelf solution across a wide range of travel distances.
Each spring is formed from A2 (304) stainless steel wire with a nominal diameter of 1.8 mm (approximately 0.071 in). The outer diameter spans 22–25 mm (roughly 0.87–0.98 in), and free lengths range from 15 mm to 200 mm (0.59–7.87 in), giving you precise control over spring rate and deflection. The Y-type (open-coil, cylindrical) geometry provides linear load characteristics across the compression stroke.
Typical use cases include jig and fixture clamping systems that require repeatable return force, valve and actuator assemblies in light industrial automation, and DIY mechanical projects such as custom drawer slides, door latches, and robotics linkages where corrosion resistance is essential for long service life.
✅ Key Features of These Compression Springs
🔩 A2 Stainless Steel Construction
Made from A2 (304) grade stainless steel wire, offering solid resistance to oxidation, moisture, and mild chemical exposure — keeping springs functional in humid or outdoor-adjacent environments.
📐 Precise Wire & OD Dimensions
Wire diameter of exactly 1.8 mm with outer diameters of 22 mm, 24 mm, or 25 mm ensures consistent fit in standard bores and around standard shafts without modification.
📏 Wide Length Range
Free lengths from 15 mm to 200 mm (0.59–7.87 in) in a single product listing — choose the length that matches your required working deflection and solid height.
🔄 Y-Type Open-Coil Geometry
The cylindrical open-coil (Y-type) design delivers a linear spring rate, predictable load-deflection behavior, and easy installation over a guide pin or inside a bore.
📦 Flexible Pack Quantities
Available in packs of 1, 2, 5, or 10 pieces depending on the size selected — order just what you need for prototyping or stock up for production runs.
🛠️ Broad Application Compatibility
Suited for jigs, fixtures, valves, actuators, robotics, drawer mechanisms, door hardware, and general mechanical assemblies requiring reliable compression return force.
