The hex body allows a standard wrench or die stock to drive the tool, making it practical for field repairs and bench work. At 1.96 pounds, the die is built for repeated use in trade and industrial settings. Plumbers, pipefitters, electricians, and maintenance technicians reach for rethreading dies when a fastener or threaded fitting has been damaged and replacement is not the preferred option.\u003c\/p\u003e\n\u003cp\u003eThis die is suited for restoring 6-40 NF unified fine thread profiles on bolts, studs, and threaded rod encountered in light mechanical assemblies, electrical enclosures, and equipment maintenance applications. The 6-40 thread size is common in instrumentation, small fasteners, and precision mechanical hardware. The import designation indicates this is a cost-effective option for shops and service vans that require a functional rethreading die without the cost of a domestic-grade tool. It is appropriate for use in both residential and light commercial service environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e6-40 NF thread form for unified fine thread restoration\u003c\/li\u003e\n  \u003cli\u003eCarbon steel construction for durability across repeated use\u003c\/li\u003e\n  \u003cli\u003eHex body profile accepts standard wrenches and die stocks\u003c\/li\u003e\n  \u003cli\u003eRestores damaged or corroded external threads without full re-cutting\u003c\/li\u003e\n  \u003cli\u003eCompact form factor suitable for field service kits and toolboxes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style rethreading die for use on 6-40 NF unified fine thread external fasteners and threaded components in light mechanical, electrical, and instrumentation applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eRethreading dies are installed and driven by a licensed or experienced trade technician using a properly sized die stock or wrench that matches the hex body. Before chasing threads on installed equipment, de-energize electrical systems and relieve any system pressure per applicable safety codes. Apply cutting oil to the die and workpiece before use to reduce heat and extend tool life. Do not use a rethreading die as a substitute for a full cutting die when new threads are required on unthreaded stock.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 6-40 NF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Unified Fine (NF)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Style\u003c\/strong\u003e: Hex\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Carbon Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.96 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 1\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: EAGLE CUTTING TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CHD-640-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233633075506,"sku":"CHD-640-I","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307622055.png?v=1780105224","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-chd-640-i-6-40-nf-hex-rethreading-die","provider":"Voomi Supply","version":"1.0","type":"link"}
