With a 1\/2-13 UNC thread size and an overall length of 0.5 inches (1D length-to-diameter ratio), this insert is manufactured from 304 stainless steel with a bright, uncoated finish. The tanged design allows for installation using a standard Heli-Coil insertion tool, then tang removal after seating. Machinists, maintenance technicians, and field repair crews use these inserts to repair stripped or damaged threads in metal components across industrial, HVAC, and mechanical service applications.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for applications requiring a reliable UNC thread repair or thread reinforcement in aluminum, cast iron, magnesium, or other softer base materials. The 1\/2-13 thread size is common in structural fastener applications, equipment housings, and mechanical assemblies. At 0.5 inches in length, it is appropriate for thinner material sections or shallow-boss thread repairs. The 1D length-to-diameter ratio makes it a standard fitment for most general-purpose thread repair needs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-13 UNC thread size for compatibility with standard fractional fasteners\u003c\/li\u003e\n  \u003cli\u003e0.5 inches overall length with 1D length-to-diameter ratio for shallow-boss installations\u003c\/li\u003e\n  \u003cli\u003e304 stainless steel construction for corrosion resistance in demanding environments\u003c\/li\u003e\n  \u003cli\u003eTanged design enables controlled installation with a standard insertion tool\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish  -  no plating to affect thread tolerance\u003c\/li\u003e\n  \u003cli\u003e4-7\/8 free coils for consistent thread engagement along the insert length\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard free running helical coil insert for 1\/2-13 UNC tapped holes requiring thread repair or reinforcement in metal base materials.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or qualified technician using the appropriately sized Heli-Coil tap and installation tool for 1\/2-13 inserts. The parent material must be drilled and tapped to the correct oversize specification before inserting. Once the insert is driven to the proper depth, the drive tang is broken off using a tang break-off tool. Always de-energize and lock out any equipment before performing thread repair work on machinery or assemblies.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Insert Length\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength to Diameter Ratio\u003c\/strong\u003e: 1D\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Free Coils\u003c\/strong\u003e: 4-7\/8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTang\u003c\/strong\u003e: Tanged\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 304\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Inserts\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0117 pounds\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: HELI-COIL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: A1185-8CN500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELI-COIL","offers":[{"title":"Default Title","offer_id":51972429807922,"sku":"A1185-8CN500","price":15.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c8549bfef9fd46117f170d16aa78a54d.jpg?v=1789968603","url":"https:\/\/voomisupply.com\/products\/heli-coil-a1185-8cn500-free-running-insert-1-2-13-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
