0.8mm Wire Diameter 304 Stainless Steel Conical Cone Compression Spring Springs

The format follows the pattern: wire diameter × free length / outer diameter × total length – coil count. For example, "0.8x5/6x14-7" means: 0.8mm wire diameter, 5mm free length, 6mm outer diameter, 14mm total reference length, 7 coils. Always cross-reference these values against your design's spring pocket dimensions before ordering.

A conical spring can compress to a very low solid height — in many cases nearly flat — because each coil nests inside the one below it as the spring compresses. This makes conical springs ideal for applications with strict height constraints, such as button mechanisms, flush-mount assemblies, and nested spring stacks where a cylindrical spring would be too tall at full compression.

Yes. 304 stainless steel offers good corrosion resistance in most outdoor, humid, and light chemical environments due to its chromium content (typically 18%). It is not recommended for prolonged exposure to chloride-rich environments (such as saltwater or marine applications) — for those, 316 stainless steel would be more appropriate. For standard indoor and light outdoor DIY use, 304 is a reliable choice.

Measure three key dimensions in your assembly: (1) the spring pocket or seat outer diameter — your spring's OD should be slightly smaller; (2) the available free height — your spring's free length should fit within this space; and (3) the required compressed height — ensure the spring's solid height (coil count × wire diameter) is less than your minimum working height. Match these against the variant size codes listed above.

Yes. The small wire diameter (0.8mm) and compact conical profile make these springs well-suited for button contacts, battery terminals, and PCB-mounted spring contacts. The 304 stainless steel material is non-magnetic and does not require additional plating for most electronic applications. Verify the spring's OD and free length against your PCB footprint or housing pocket before use.

Each size variant is available in packs of 1, 5, 10, 20, or 50 pieces. Larger pack sizes are priced at a lower per-unit cost, making them economical for prototyping runs, small-batch production, or stocking a parts drawer. Select your preferred quantity using the QTY(PCS) option above.

304 stainless steel retains reasonable mechanical properties up to approximately 300°C (572°F) for short-term exposure, though spring rate and fatigue life may decrease at elevated temperatures. For continuous high-temperature service above 150°C (302°F), consider springs made from high-temperature alloys. For typical DIY, electronics, and light mechanical applications at ambient temperatures, these springs perform reliably.
