The kit includes 36 stainless wire inserts spanning three length sizes, along with the drill, tap, installation tool, and tang removal tool needed to complete the repair without sourcing additional hardware. Licensed HVAC technicians, machinists, maintenance mechanics, and industrial service professionals use this kit when a tapped hole has failed and a replacement insert is the correct fix. Insert length runs from 4 mm at the shortest to 7.00 mm at the longest, giving the installer flexibility across different material thicknesses.\u003c\/p\u003e\n\u003cp\u003eThis kit is suited for light-duty metric thread repair work in residential and commercial maintenance environments, manufacturing floors, and field service situations where M3.5 x 0.60 metric coarse threads are present. Typical applications include restoring threads in aluminum housings, equipment enclosures, and small mechanical assemblies. The included drill size is 0.1440 decimal inch (wire size 27), which corresponds directly to the correct pre-tap hole diameter for this insert size. Twelve inserts are provided for each of the three available length sizes, allowing the technician to match insert length to the specific material being repaired.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM3.5 x 0.60 metric coarse thread size for standard metric fastener compatibility\u003c\/li\u003e\n  \u003cli\u003e36 inserts total across three length sizes: 4 mm, 5.3 mm, and 7.00 mm (12 inserts per size)\u003c\/li\u003e\n  \u003cli\u003eComplete kit includes drill, tap, installation tool, and tang removal tool\u003c\/li\u003e\n  \u003cli\u003eTang removal tool size 3\/32 included for clean post-installation finishing\u003c\/li\u003e\n  \u003cli\u003eInstallation tool part number 7751-3.5 and tap part number 2087-3.5 are matched components\u003c\/li\u003e\n  \u003cli\u003eInsert package part number R1084-3.5 for reorder reference\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style thread repair solution for any application requiring M3.5 x 0.60 metric coarse threaded inserts in metal base materials.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThread repair inserts of this type are installed by machinists, maintenance mechanics, or trained service technicians using the drill, tap, and installation tool included in the kit. The damaged hole must be drilled to the correct diameter using the included 0.1440 inch drill before tapping. After the insert is driven to the correct depth, the tang is broken off using the 3\/32 tang removal tool. Always follow the insert manufacturer's installation sequence and ensure the workpiece is secured before drilling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKit Type\u003c\/strong\u003e: Threaded Insert\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thread Size\u003c\/strong\u003e: M3.5 x 0.60\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Inserts\u003c\/strong\u003e: 36\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInserts Per Size\u003c\/strong\u003e: 12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length (nominal)\u003c\/strong\u003e: 5.3 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShortest Insert Length\u003c\/strong\u003e: 4 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLongest Insert Length\u003c\/strong\u003e: 7.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Size (Wire)\u003c\/strong\u003e: 27\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Size (Decimal Inch)\u003c\/strong\u003e: 0.1440 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes Drill\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes Tap\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes Installation Tool\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes Tang Removal Tool\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTang Removal Tool Size\u003c\/strong\u003e: 3\/32\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInstallation Tool Part Number\u003c\/strong\u003e: 7751-3.5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Part Number\u003c\/strong\u003e: 2087-3.5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Package Part Number\u003c\/strong\u003e: R1084-3.5\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: 5403-3.5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELI-COIL","offers":[{"title":"Default Title","offer_id":51971670573362,"sku":"5403-3.5","price":285.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6c4aace85ee296fa33bc9e94fa89fd77.jpg?v=1789958834","url":"https:\/\/voomisupply.com\/products\/heli-coil-5403-3-5-thread-repair-kit-m3-5-x-0-60-36-inserts","provider":"Voomi Supply","version":"1.0","type":"link"}
