Y Type Compression Spring 1mm Wire OD 6–8mm — Reliable A2 Stainless Steel for Precision Applications

Finding a compact compression spring that holds its load cycle after cycle is a real challenge for makers, repair technicians, and mechanical engineers working on tight-tolerance assemblies. These Y type compression springs are designed for exactly that — delivering consistent return force in confined spaces where standard springs simply won't fit.

Each spring is manufactured from A2 (304) stainless steel wire with a diameter of 1 mm (0.039 in). The outer diameter (OD) ranges from 6 mm to 8 mm (approximately 0.24 in to 0.31 in), and free lengths span from 10 mm to 305 mm (0.39 in to 12.0 in) depending on the variant selected. Packs are available in quantities of 1, 5, 10, 20, or 50 pieces to suit both prototyping and production runs.

These springs are well-suited for DIY mechanical projects requiring small-diameter return springs, electronic device repair needing compact load elements, and light industrial machinery maintenance where corrosion resistance is critical in humid or outdoor environments.

🔧 Compatibility: Suitable for spring seats, plunger mechanisms, valve assemblies, and general-purpose compression applications requiring an OD of 6 mm, 7 mm, or 8 mm with 1 mm wire diameter.

✅ Key Features of These Y Type Compression Springs

🔩 A2 Stainless Steel Construction

Made from A2 (304) stainless steel, these compression springs resist rust, oxidation, and mild chemical exposure — ideal for outdoor, humid, or marine-adjacent environments.

📐 Precise 1mm Wire Diameter

The 1 mm wire diameter provides a consistent spring rate across all length variants, ensuring predictable deflection behavior in precision mechanical assemblies.

📏 Wide Length Range: 10mm to 305mm

Available in free lengths from 10 mm (0.39 in) to 305 mm (12.0 in), covering a broad range of stroke and travel requirements in a single product family.

🎯 Three OD Options: 6mm, 7mm, 8mm

Choose from outer diameters of 6 mm, 7 mm, or 8 mm to match your bore or housing diameter precisely — no guesswork, no shimming required.

📦 Flexible Pack Quantities

Order in packs of 1, 5, 10, 20, or 50 pieces. Smaller packs suit prototyping and repair; larger packs reduce per-unit cost for production or workshop stock.

⚙️ Y Type Open-Coil Design

The open-coil Y type geometry allows for controlled compression travel and easy integration into plunger, valve, and return-spring applications without binding.

❓ Frequently Asked Questions

How do I choose the right OD — 6mm, 7mm, or 8mm?

Measure the inner diameter of your bore, housing, or guide rod. The spring OD should be slightly smaller than the bore ID to allow free movement without binding. For a 7 mm bore, the 6 mm OD spring is typically a good fit; for an 8–9 mm bore, choose the 7 mm or 8 mm OD variant.

What free length should I select for my application?

The free length should be longer than your required compressed length plus your desired travel (stroke). As a general rule: Free Length = Compressed Length + Required Travel. Browse the "Item Length & Size" variant options to find the closest match to your design requirement.

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

These springs are designed for light-to-medium duty compression applications with a 1 mm wire diameter. They are well-suited for return springs, plunger mechanisms, valve springs, and similar applications. For heavy-load structural applications, a larger wire diameter would be recommended.

Will A2 stainless steel rust or corrode outdoors?

A2 (304) stainless steel offers good resistance to atmospheric corrosion, moisture, and mild chemicals. It performs reliably in outdoor, humid, and light marine environments. For highly aggressive saltwater or chemical exposure, A4 (316) stainless would be a stronger choice.

Are these compatible with standard spring plunger and ball detent assemblies?

Yes — the 6 mm, 7 mm, and 8 mm OD variants are commonly used in spring plunger, ball detent, and push-button return mechanisms. Verify the bore diameter and required travel in your assembly before selecting a variant.

Why does the pack quantity change at longer lengths?

Longer springs require more material per piece, so pack quantities are adjusted accordingly. Shorter lengths (10–50 mm) are available in packs of up to 50 pcs, while longer lengths (120–305 mm) come in smaller packs of 1–5 pcs. This keeps pricing fair across all size options.

Can I use these springs in electronic devices or small appliances?

Yes. The compact 1 mm wire diameter and small OD range make these springs suitable for battery contacts, push-button switches, keyboard mechanisms, and other consumer electronics repair or prototyping applications.

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
