The die features precision-cut threads that are accurately formed to produce consistent, exact threading results on each pass. It is heat treated and tempered to achieve file-hard thread faces, which extends service life under repeated use. The hex body measures 1 inch across the flats, making it compatible with standard die stocks and holders used in bench and hand threading work. This is a package of 2 dies.\u003c\/p\u003e\n\u003cp\u003eThis die is suited for threading 4-40 NC fasteners in light manufacturing, repair, and maintenance applications. It is commonly used by machinists, maintenance technicians, and skilled tradespeople who need to cut or restore external threads on small machine screws. The hand-cutting design makes it appropriate for low-volume threading tasks where a threading machine is not required. It performs well in shop environments for both new thread cutting and chasing damaged threads on existing hardware.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-40 national coarse thread specification for small machine screw applications\u003c\/li\u003e\n  \u003cli\u003ePrecision-formed threads deliver consistent, exact thread profiles\u003c\/li\u003e\n  \u003cli\u003eHeat treated and tempered for file-hard thread faces and extended service life\u003c\/li\u003e\n  \u003cli\u003eHex body at 1 inch across the flats fits standard die stocks and holders\u003c\/li\u003e\n  \u003cli\u003eDesigned for hand cutting applications — no threading machine required\u003c\/li\u003e\n  \u003cli\u003eSold as a package of 2 dies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a hand-threading die for 4-40 national coarse machine screw applications; fits standard 1-inch hex die stocks and holders used in bench threading work.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThread cutting with a hex die is typically performed by machinists or maintenance tradespeople using a die stock or tap-and-die wrench. Secure the workpiece firmly before beginning. Apply cutting oil to the die and workpiece to reduce heat and improve thread finish during the cutting pass. Reverse the die periodically to clear chips and prevent thread damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Specification\u003c\/strong\u003e: 4-40 National Coarse (NC)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDie Type\u003c\/strong\u003e: Hex Threading Die\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAcross Flats\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Hand cutting\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.14 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: CENTURY DRILL TOOL CO INC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 96101\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CENTURY DRILL \u0026 TOOL","offers":[{"title":"Default Title","offer_id":51563167678770,"sku":"96101","price":16.28,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/acb6f5c39ad92dbc1d605bf694e0d762_73e90d59-266b-4112-8975-bd8235cb1975.jpg?v=1786492056","url":"https:\/\/voomisupply.com\/products\/century-drill-tool-co-inc-96101-4-40-nc-hex-threading-die","provider":"Voomi Supply","version":"1.0","type":"link"}
