It is used to cut internal threads in a variety of materials by hand. The straight flutes are ground to promote rapid chip removal, supporting efficient threading throughout the cut. This tap produces a Class 2B thread fit, which is appropriate for routine maintenance and repair work where high-precision tolerance threads are not required. A licensed tradesperson or experienced maintenance technician is the typical installer.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for rethreading and repair applications in residential, commercial, and light industrial maintenance settings. It performs well when threading soft to medium-hardness materials by hand. Because it targets Class 2B thread accuracy, it is most appropriate for general-purpose fastening applications rather than precision-critical assemblies. The recommended drill bit size for tap preparation is 11\/16 inch. This tap is sold in a package of 6 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4 inch-16 National Fine (NF) thread specification\u003c\/li\u003e\n  \u003cli\u003eCarbon steel construction for general-purpose hand threading\u003c\/li\u003e\n  \u003cli\u003eStraight flutes ground for rapid chip removal and efficient threading\u003c\/li\u003e\n  \u003cli\u003eProduces a Class 2B thread fit suitable for maintenance and repair\u003c\/li\u003e\n  \u003cli\u003eDesigned for hand threading in a variety of materials\u003c\/li\u003e\n  \u003cli\u003eRequires an 11\/16 inch drill bit for correct tap drill preparation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for hand tapping applications requiring a 3\/4 inch-16 National Fine thread in a range of materials; not intended for precision thread applications where tight tolerance Class 2A or 3B fits are specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap is intended for hand threading use with a standard tap wrench; do not use in a power drill or tap driver without confirming the tool is rated for hand-tap sizes. Always use the specified 11\/16 inch drill bit to prepare the pilot hole before tapping. Apply a suitable cutting fluid for the base material to extend tap life and reduce the risk of tap breakage. Back the tap off periodically to break chips and clear the flutes during the threading operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4 inch-16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: National Fine (NF)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Type\u003c\/strong\u003e: Fractional Hand Tap\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Carbon Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Class Produced\u003c\/strong\u003e: Class 2B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecommended Drill Bit\u003c\/strong\u003e: 11\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.68 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: 97118\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CENTURY DRILL \u0026 TOOL","offers":[{"title":"Default Title","offer_id":51559445823794,"sku":"97118","price":89.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/79cbbd4ffab967ab35ecafd3f97666ca_3beeacb2-8e89-4c0c-8a6c-0e8106d40696.jpg?v=1786432651","url":"https:\/\/voomisupply.com\/products\/century-drill-97118-3-4-16-nf-fractional-hand-tap-carbon-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
