It engages the insert's drive tang and winds the coil into the threaded bore without damaging the insert geometry or host material. Licensed HVAC technicians, machinists, maintenance mechanics, and field service pros use this tool when installing HELI-COIL wire thread inserts to restore or reinforce stripped threads in metal, plastic, or composite components. The tool is lightweight at 0.33 pounds and sized for one-hand operation in tight service spaces.\u003c\/p\u003e\n\u003cp\u003eThis tool is used wherever 1\/4-20 UNC HELI-COIL thread inserts are installed by hand. Common applications include thread repair on HVAC equipment housings, electrical enclosures, pump bodies, compressor brackets, and general mechanical assemblies. It is suited for both shop bench work and in-field service calls where a power driver is not appropriate or practical. The hand tool format gives the installer controlled torque feel to seat the insert flush without overdriving.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDesigned for 1\/4-20 UNC thread insert installation by hand\u003c\/li\u003e\n  \u003cli\u003eEngages insert drive tang for controlled, damage-free winding\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.33 pounds for single-hand use in tight spaces\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard HELI-COIL 1\/4-20 wire thread inserts\u003c\/li\u003e\n  \u003cli\u003eNo power source required  -  suitable for field and bench use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with HELI-COIL 1\/4-20 UNC wire thread inserts as an OEM-style hand installation tool for that insert size and thread standard.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, maintenance technicians, or field service pros following standard thread repair procedures. Before installing any thread insert, ensure the host bore has been drilled and tapped to the correct HELI-COIL tap size for 1\/4-20 UNC. Engage the tool tang slot onto the insert tang and wind the insert in clockwise until it sits one half turn below the surface. After installation, break off the drive tang using the tang break-off tool if required by the application.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Type\u003c\/strong\u003e: Hand Installation Tool\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Thread Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.33 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291800\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: 2288-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELI-COIL","offers":[{"title":"Default Title","offer_id":52080311533874,"sku":"2288-4","price":82.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5804a9d12dd78872389c520433f95637.jpg?v=1790055410","url":"https:\/\/voomisupply.com\/products\/heli-coil-2288-4-thread-insert-tool-1-4-20-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
