A2 Stainless Steel Compression Springs — Reliable Elastic Force for Every DIY Build

When a worn-out spring causes a mechanism to fail mid-project, finding an exact replacement can be frustrating. These A2 stainless steel Y type compression springs are designed for makers, repair technicians, and workshop enthusiasts who need a dependable, corrosion-resistant spring in precise metric dimensions — without compromise.

Each spring is manufactured from A2 (304) stainless steel wire with a diameter of 1.6 mm (0.063 in). The outer diameter spans 14 mm to 16 mm (0.55 in to 0.63 in), and free lengths range from 10 mm to 200 mm (0.39 in to 7.87 in). Available in packs of 1, 2, 5, 10, or 20 pieces depending on the selected length variant.

Ideal for use in mechanical assemblies requiring consistent return force, these compression springs suit applications such as valve mechanisms and actuator returns, jig and fixture spring-loading in workshop setups, and DIY electronics enclosures or switch-return mechanisms where a compact stainless spring is needed.

🔩 Compatibility: Suitable for standard metric spring seats and bores accepting 14 mm, 15 mm, or 16 mm OD springs. Verify bore clearance and free length before ordering.

✅ Key Features of These A2 Stainless Steel Compression Springs

🦾 A2 (304) Stainless Steel Construction

Resists oxidation and corrosion in humid or mildly acidic environments, extending service life in demanding workshop and outdoor repair applications.

📏 Precise Metric Dimensions

Wire diameter 1.6 mm, OD 14–16 mm, free length 10–200 mm — exact sizing ensures drop-in compatibility with metric spring pockets and guides.

🔄 Y Type Compression Profile

Consistent coil pitch and closed ends deliver uniform load distribution and stable axial compression across the full travel range.

📦 Flexible Pack Quantities

Choose from 1, 2, 5, 10, or 20 pieces per order depending on your project scale — from single-unit repairs to batch workshop builds.

⚙️ Wide Length Range

Free lengths from 10 mm to 200 mm cover a broad spectrum of travel requirements, from compact switch returns to longer actuator assemblies.

🛡️ Durable Finish, No Coating Required

The natural stainless steel surface requires no additional plating or coating, maintaining dimensional accuracy and avoiding flaking in precision assemblies.

❓ Frequently Asked Questions

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

Measure the distance between the spring seats in your assembly when fully extended (unloaded). Select a free length equal to or slightly longer than that measurement. The spring will compress to your working length under load. If you need a specific compressed length, contact us to confirm the spring rate and solid height for your chosen variant.

What outer diameter should I select — 14 mm, 15 mm, or 16 mm?

Choose an OD that fits freely inside your spring bore or guide tube with a small clearance (typically 0.5–1 mm). For a 15 mm bore, a 14 mm OD spring is a good fit. Always verify the bore diameter in your assembly before ordering.

Are these springs strong enough for load-bearing mechanical assemblies?

With a 1.6 mm wire diameter and 14–16 mm OD, these springs provide moderate elastic force suitable for light-to-medium duty applications such as valve returns, switch mechanisms, and jig fixtures. For heavy-load structural applications, a larger wire diameter or OD is recommended. Contact us to confirm suitability for your specific load requirements.

Will A2 stainless steel rust or corrode outdoors?

A2 (304) stainless steel offers good corrosion resistance in most outdoor and humid environments. It resists rust from rain and moisture effectively. However, in highly saline or chloride-rich environments (e.g., coastal or marine settings), A4 (316) stainless steel is recommended for superior corrosion resistance.

Can I use these springs in electronics or precision instrument enclosures?

Yes. The uncoated stainless steel surface is non-magnetic (A2/304 is austenitic) and does not flake or shed particles, making these springs suitable for use in switch-return mechanisms, battery contacts, and precision instrument assemblies where contamination must be minimized.

How do I read the variant naming format (e.g., "1.6x14x20mm")?

The format is Wire Diameter × Outer Diameter × Free Length. So "1.6x14x20mm" means: 1.6 mm wire, 14 mm OD, 20 mm free length. The quantity in brackets (e.g., "5 pcs") indicates how many springs are included in that variant pack.

What is the difference between the 5-pack and 10-pack or 20-pack options?

For lengths up to 50 mm, packs of 5, 10, and 20 pieces are available — ideal for batch repairs or stocking your workshop. For longer springs (60 mm and above), packs of 1, 2, and 5 pieces are offered, reflecting the larger size per unit. Select the quantity that matches your project needs.

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
