The kit uses a coiled wire threaded insert that installs into a re-drilled and re-tapped hole, creating a durable helical thread form that meets or exceeds the strength of the original material. Each kit includes a drill bit, a 5\/8-18 UNF tap, an installation tool, and a tang removal tool, along with 6 inserts at 0.938 inches in length. Licensed trades, machinists, and field service technicians use this kit to salvage damaged tapped holes without replacing the entire component.\u003c\/p\u003e\n\u003cp\u003eThis kit is suited for repair work on aluminum, cast iron, steel, and other base materials where thread stripping is common from overtorque or corrosion. Typical applications include engine components, hydraulic manifolds, industrial equipment housings, and structural fastener locations requiring a 5\/8-18 UNF thread form. The 0.938-inch insert length provides solid thread engagement for high-load fastener situations. The included tooling makes this a self-contained solution for both shop and field repairs without sourcing separate components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRepairs 5\/8-18 UNF threaded holes using a coiled wire insert design\u003c\/li\u003e\n  \u003cli\u003eInsert length of 0.938 inches for strong thread engagement\u003c\/li\u003e\n  \u003cli\u003eIncludes drill bit, UNF tap (part number 8193-10), installation tool (part number 2299-10), and tang removal tool\u003c\/li\u003e\n  \u003cli\u003eComes with 6 inserts (insert package part number R1191-10)\u003c\/li\u003e\n  \u003cli\u003eThread standard is UNF  -  fine-thread series for vibration-prone and precision applications\u003c\/li\u003e\n  \u003cli\u003eSelf-contained kit requires no additional tooling to complete the repair\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a thread repair solution for any application requiring a 5\/8-18 UNF threaded insert.

Always isolate or de-energize the equipment before beginning any thread repair on structural or mechanical components. Drill to the specified oversize diameter, tap the new hole with the included tap, then drive the insert using the installation tool. After seating the insert, remove the drive tang with the included tang removal tool per standard HELI-COIL procedure.\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: 5\/8-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.938 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Inserts\u003c\/strong\u003e: 6\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 (part number 8193-10)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes Installation Tool\u003c\/strong\u003e: Yes (part number 2299-10)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes Tang Removal Tool\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Package Part Number\u003c\/strong\u003e: R1191-10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2 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: 5402-10\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELI-COIL","offers":[{"title":"Default Title","offer_id":52003383935282,"sku":"5402-10","price":322.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/baa71c5f2c922bf47cc37224b261859e.jpg?v=1789998752","url":"https:\/\/voomisupply.com\/products\/heli-coil-5402-10-thread-repair-kit-5-8-18-unf-threaded-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
