Manufactured from 18-8 stainless steel, the insert delivers corrosion resistance and hardness that typically exceeds the strength of the mating screw. The overall installed length is 0.164 inches, placing it in the 1D length-to-diameter ratio class, which is suited for applications where thread depth is limited. A tanged design is used for installation with a standard drive tool, and the insert features 3-1\/2 free coils. Electricians, millwrights, mechanics, and maintenance technicians routinely install these inserts to restore stripped threads or to establish strong threads in softer base materials.\u003c\/p\u003e\u003cp\u003eThis insert is used in light-duty to medium-duty fastening applications across HVAC equipment, electrical enclosures, plumbing fixtures, and general mechanical assemblies. The 8-32 UNC thread form is one of the most common machine screw sizes in trade work, making this insert a practical repair and new-installation solution in both shop and field environments. The single-insert packaging is suited for targeted repairs, while the minimum order quantity supports stocking in service vehicles or maintenance toolboxes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e8-32 UNC thread form for compatibility with standard machine screws\u003c\/li\u003e\n\u003cli\u003e18-8 stainless steel construction for corrosion resistance and durability\u003c\/li\u003e\n\u003cli\u003eTanged design for installation with a standard HELI-COIL drive tool\u003c\/li\u003e\n\u003cli\u003e1D length-to-diameter ratio at 0.164 inches overall insert length for shallow-thread applications\u003c\/li\u003e\n\u003cli\u003e3-1\/2 free coils provide consistent thread engagement across the insert length\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style thread repair and thread installation insert for any parent material tapped to the HELI-COIL 8-32 UNC insert tap specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires the parent material to be drilled and tapped with the correct HELI-COIL tap for the 8-32 insert size before the insert is driven in. A dedicated HELI-COIL installation tool is used to wind the insert into the tapped hole. After installation, the tang must be broken off using a tang break-off tool before the fastener is installed. Power down or de-energize any equipment before performing thread repair work on electrical or HVAC components.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 8-32\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: 0.164 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: 3-1\/2\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: 18-8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0004 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: A1185-2EN164\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELI-COIL","offers":[{"title":"Default Title","offer_id":51972389372210,"sku":"A1185-2EN164","price":34.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/328326aca268678d94b3b4815a5f68cc.jpg?v=1789967387","url":"https:\/\/voomisupply.com\/products\/heli-coil-a1185-2en164-free-running-insert-8-32-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
