Manufactured from high carbon steel to ASTM A228 standards, this coil measures 0.039 inches in diameter at 17 gauge and delivers 247 feet of usable wire per coil. It is designed for fabrication shops, maintenance technicians, and trade professionals who form custom springs, wire forms, and mechanical components. The ASTM A228 designation confirms the wire meets established standards for high-carbon, cold-drawn spring steel quality.\u003c\/p\u003e\n\u003cp\u003eThis music wire coil is suited for light industrial and mechanical trade applications where precision wire forming is required. Typical uses include fabricating compression springs, extension springs, torsion springs, and small wire assemblies. At 17 gauge and 0.039 inches in diameter, it falls in the small-diameter range appropriate for intricate form work. Maintenance professionals, tool-and-die shops, and HVAC or equipment service technicians who fabricate replacement spring components on-site will find this coil a practical bench-stock item.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh carbon steel construction meets ASTM A228 standard for spring-quality music wire\u003c\/li\u003e\n  \u003cli\u003e17 gauge, 0.039 inch diameter provides consistent cross-section for repeatable spring forming\u003c\/li\u003e\n  \u003cli\u003e247-foot coil length maximizes yield per unit for high-volume fabrication tasks\u003c\/li\u003e\n  \u003cli\u003eTempered finish delivers controlled hardness and spring-back for demanding mechanical applications\u003c\/li\u003e\n  \u003cli\u003eSold as a single coil with no minimum order above one unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose spring-quality music wire coil suitable for any application requiring ASTM A228-compliant high carbon steel wire at 17 gauge (0.039 inches in diameter).\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eMusic wire should be cut and formed using tools rated for high carbon spring steel to avoid burring or work-hardening at the cut point. Wear appropriate eye and hand protection when uncoiling and cutting spring wire, as stored energy in the coil can cause sudden release. No heat treatment is required before use; the wire arrives in a tempered state ready for forming. Follow applicable shop safety standards and equipment manufacturer guidelines when fabricating replacement spring components.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Type\u003c\/strong\u003e: Tempered Music Wire Coil\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGauge\u003c\/strong\u003e: 17\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Diameter\u003c\/strong\u003e: 0.039 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 247 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Carbon Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASTM A228\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShipping Weight\u003c\/strong\u003e: 1.4 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31152200\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 21039\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION BRAND","offers":[{"title":"Default Title","offer_id":51539402195250,"sku":"21039","price":25.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fe2d4720b19ae39afb8cbe59e9bf6070.jpg?v=1785839297","url":"https:\/\/voomisupply.com\/products\/precision-brand-21039-tempered-music-wire-coil-17-gauge","provider":"Voomi Supply","version":"1.0","type":"link"}
