Built from high-speed steel (HSS) with a gold oxide coating, this tap resists heat buildup and wear during threading operations. It features 3 straight flutes and a plug chamfer that starts the thread gradually, making it suitable for through-hole and partially blind threading applications. Overall length is 2 inches, and the thread limit is H2, indicating a standard tolerance class appropriate for general-purpose UNF fastener fits. Right-hand thread direction is standard for most threading work.\u003c\/p\u003e\u003cp\u003eThis tap is used in machine shop, maintenance, and fabrication settings where 6-40 UNF threads are required. The plug chamfer style makes it a general-purpose choice, appropriate for both manual tapping with a tap wrench and use in drill press or tapping machine setups. It is commonly used by machinists, maintenance technicians, and tool-and-die professionals working with small-diameter fasteners in metal components.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e6-40 UNF thread size with 40 threads per inch for fine-thread applications\u003c\/li\u003e\n\u003cli\u003e3 straight flutes for efficient chip clearance in through-hole and shallow blind-hole threading\u003c\/li\u003e\n\u003cli\u003ePlug chamfer style provides gradual thread engagement for general-purpose use\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction withstands heat and abrasion during cutting\u003c\/li\u003e\n\u003cli\u003eGold oxide coating reduces friction and improves surface lubricity\u003c\/li\u003e\n\u003cli\u003eH2 thread limit ensures standard tolerance class fit for UNF fastener applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or working tap for applications requiring 6-40 UNF internal threads with a plug chamfer and right-hand thread direction.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThreading operations should be performed by qualified machinists or maintenance technicians familiar with tap selection and proper cutting technique. Always use appropriate cutting fluid for the material being tapped to extend tap life and improve thread finish. Secure the workpiece firmly before starting and back off the tap periodically to break chips and prevent tap breakage. Inspect the tap for wear or damage before each use, particularly when working with hard or abrasive materials.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 6-40 UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Gold Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: IMPORT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: BDNA-20752\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IMPORT-GENERIC","offers":[{"title":"Default Title","offer_id":51715720544562,"sku":"BDNA-20752","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/107155a99040ee4c18875a9621ddb478.jpg?v=1788517674","url":"https:\/\/voomisupply.com\/products\/import-bdna-20752-straight-flute-tap-6-40-unf-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
