These 0.8mm wire diameter conical cone compression springs are designed for makers, engineers, and hobbyists who need consistent spring force in tight or tapered spaces without sacrificing durability.\u003c\/p\u003e\n\u003cp\u003eEach spring is formed from 304 stainless steel wire with a diameter of 0.8mm (approximately 0.031 in). The conical body tapers from a larger outer diameter down to a smaller end, allowing the spring to compress nearly flat — ideal for space-constrained designs. Sizes across this listing range from approximately 5mm to 15mm in free length (0.20–0.59 in), with outer diameters spanning roughly 6mm to 24.3mm (0.24–0.96 in) and coil counts from 4 to 13 active coils. See variant options for exact dimensions per size.\u003c\/p\u003e\n\u003cp\u003eTypical use cases include DIY automation projects requiring low-profile return springs, electronic device button mechanisms needing conical compression springs for tactile feedback, and small mechanical assemblies such as valve seats, latches, and jig fixtures where a tapered spring profile enables nested or flush-mount installation.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-compat\"\u003e\n\u003cspan class=\"hdiy-compat-icon\"\u003e⚙️\u003c\/span\u003e Compatible with standard spring seats, countersunk pockets, and nested spring assemblies.

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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eIs 304 stainless steel suitable for outdoor or humid environments?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eYes. 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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow do I select the right size for my application?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eMeasure 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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eCan these springs be used in electronic devices or PCB assemblies?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eYes. 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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat quantity options are available, and is bulk pricing offered?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eEach size variant is available in packs of 1, 5, 10, 20, or 50 pieces.
