Compression Spring A2 Stainless Steel 1.6mm Wire — Reliable Force for Every DIY Application

When a project demands consistent return force without the risk of rust or fatigue failure, finding the right compression spring can be frustrating. Undersized springs collapse under load; oversized ones won't fit the bore. These A2 stainless steel Y-type compression springs are engineered for makers, engineers, and workshop professionals who need a dependable, corrosion-resistant solution across a wide range of diameters and lengths.

Each spring is wound from 1.6 mm diameter A2 (304) stainless steel wire, offering a good balance of tensile strength and corrosion resistance. Outer diameters span 10 mm to 13 mm (approximately 0.39 in to 0.51 in), and free lengths range from 10 mm to 200 mm (approximately 0.39 in to 7.87 in), giving you the flexibility to match the exact bore and travel requirements of your assembly.

Typical use cases include electronic enclosure latches and button mechanisms requiring precise return force, light-duty valve and actuator assemblies in fluid-handling equipment, and jig-and-fixture clamping systems in woodworking or metalworking shops where corrosion resistance is essential.

🔩 Compatibility: Suitable for spring bores accepting 10–13 mm OD. Verify free length and spring rate against your load requirements before ordering. Available in multiple quantity packs for prototyping or production runs.

✅ Key Features of These Compression Springs

🧲 A2 (304) Stainless Steel Wire

Wound from 1.6 mm A2 stainless steel, these springs resist oxidation and mild chemical exposure, making them suitable for humid or lightly corrosive environments.

📐 Wide Size Range

OD options of 10, 11, 12, and 13 mm combined with free lengths from 10 mm to 200 mm let you select the exact geometry your application demands.

⚙️ Y-Type Open-Coil Design

The Y-type (open-coil) winding provides consistent pitch along the body, delivering predictable linear deflection and stable spring rate under compression.

📦 Flexible Pack Quantities

Available in packs of 1, 2, 5, 10, 20, and 50 pieces so you can order just what you need for a prototype or stock up for a production batch.

🔄 Consistent Coil Geometry

Uniform coil spacing and closed, ground ends (where applicable) ensure square seating against mating surfaces, reducing side-load and extending service life.

🛠️ Broad Application Compatibility

Fits standard spring pockets in electronic assemblies, pneumatic valves, clamping fixtures, and consumer product mechanisms requiring a 10–13 mm OD spring.

❓ Frequently Asked Questions

How do I choose the right OD and free length for my application?

Measure the bore or housing diameter your spring must fit inside — the spring OD should be 0.5–1 mm smaller than the bore for clearance. For free length, select a spring that is longer than your required compressed length plus the desired travel (stroke). If you need a specific spring rate, contact us to confirm before ordering.

What load can a 1.6 mm wire diameter spring handle?

The load capacity depends on the OD, free length, and number of active coils — all of which vary by variant. As a conservative guide, 1.6 mm wire A2 stainless springs in this OD range typically handle light to medium loads (generally under 50 N at full compression). For precise load data, please contact us with your specific variant size.

Are these springs corrosion-resistant enough for outdoor or wet environments?

A2 (304) stainless steel offers good resistance to atmospheric corrosion, fresh water, and mild chemical exposure. It is not recommended for prolonged immersion in salt water or strong acids. For marine or highly corrosive environments, consider A4 (316) stainless steel springs instead.

What does "Y-Type" mean for a compression spring?

"Y-Type" refers to an open-coil winding pattern where the coils are evenly spaced along the spring body. This design provides a consistent, predictable spring rate throughout the compression stroke and is the most common configuration for general-purpose compression springs.

Can I use these springs in electronic or PCB assemblies?

Yes. The smaller OD variants (10–11 mm) are well-suited for button return mechanisms, battery contacts, and connector retention in electronic enclosures. A2 stainless steel is non-magnetic in its annealed state, which is beneficial in many electronic applications.

Which pack size should I order for prototyping vs. production?

For prototyping or testing fit and function, the 1-piece or 5-piece packs are ideal. For small production runs or to keep spares on hand, the 10- or 20-piece packs offer better value per unit. The 50-piece pack is suited for higher-volume assembly work where consistent restocking is needed.

How do I verify the spring will fit my existing pocket or bore?

Check three dimensions: (1) bore inner diameter — must be larger than the spring OD by at least 0.5 mm; (2) pilot pin or inner guide diameter — must be smaller than the spring ID (ID = OD minus 2× wire diameter, so approximately 6.8–9.8 mm for this range); (3) pocket depth — must accommodate the compressed length of the spring at maximum load.

These o rings are a great for my ear tunnels

These o rings are a great for my ear tunnels, always loosing one here and there, I always have a new ones in the drawer. Being silicone, don't have any reactions compared to standard rubber ones I purchased at hardware stores, plus much less expensive. Purchased 16mm I'd to use on 19mm tunnels, and stay on great, might be able to get away with 17mm rings, but really happy with my choice.

Will never order from these folks again

I waited a long time and that’s all I received was the eyebolt with no threaded rod attached to it

Perfect they are really made well and I used them for my car

Perfect they are really made well and I used them for my car. The only thing I had a great for us. It took three weeks to get here. So shipping was slow.

did not include wing nuts
