At 15 gauge, the wire measures 0.035 inches in diameter and runs 306 feet per coil, giving technicians and fabricators a full working supply on a single spool. The wire is manufactured to ASTM A228 standards, which specifies high-carbon steel wire intended for mechanical spring and dynamic load applications. Its tempered condition delivers consistent tensile strength and elasticity across the length of the coil, making it suitable for repeated flex and load cycles without premature fatigue.\u003c\/p\u003e\u003cp\u003eThis wire coil is used in industrial maintenance, equipment repair, and custom spring fabrication across mechanical trades. It is appropriate for both shop-bench work and field service applications where a reliable, uniform-diameter spring wire is needed. At 306 feet per coil, the 21035 supports multiple projects from a single unit. Applications include forming compression springs, extension springs, and wire-form components in HVAC equipment, machinery, and general mechanical assemblies. The coil ships as a single unit with a package quantity of one.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eASTM A228 compliant high carbon steel construction for consistent mechanical spring performance\u003c\/li\u003e\n\u003cli\u003eTempered condition provides uniform tensile strength and fatigue resistance across the full coil length\u003c\/li\u003e\n\u003cli\u003e0.035 inch diameter at 15 gauge for precise fitment in spring-forming and wire-form applications\u003c\/li\u003e\n\u003cli\u003e306-foot coil length reduces the need for frequent resupply on larger jobs\u003c\/li\u003e\n\u003cli\u003eSingle-coil packaging with a minimum order quantity of one\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose tempered music wire coil suitable for mechanical spring fabrication and wire-form applications requiring ASTM A228 high carbon steel at 15 gauge and 0.035 inch diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eWorking with spring wire requires appropriate personal protective equipment including cut-resistant gloves and eye protection due to the stored energy and sharp cut ends produced during forming. Use proper wire-forming tools and bending fixtures to maintain consistent geometry and avoid stress concentrations. Cutting should be performed with quality wire cutters or shears rated for high-carbon steel to prevent burring. Secure the free end of the coil during unwinding to prevent uncontrolled release.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Gauge\u003c\/strong\u003e: 15\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Diameter\u003c\/strong\u003e: 0.035 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoil Length\u003c\/strong\u003e: 306 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Carbon Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Type\u003c\/strong\u003e: Tempered Music Wire\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASTM A228\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 1.4 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31152200\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PRECISION BRAND\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 21035\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION BRAND","offers":[{"title":"Default Title","offer_id":51542512894258,"sku":"21035","price":27.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/04898c9194df07954b56a165a946fccb_373abf96-320e-46e8-b2fe-699e1245f096.jpg?v=1785902462","url":"https:\/\/voomisupply.com\/products\/precision-brand-21035-music-wire-coil-15-gauge-0-035-in-306-ft","provider":"Voomi Supply","version":"1.0","type":"link"}
