Built from high-speed steel (HSS) with a gold oxide coating, this tap offers improved lubricity and surface hardness compared to uncoated alternatives. The taper chamfer on the leading end distributes cutting load gradually across multiple threads, making it well suited for through-hole tapping applications. Four flutes provide adequate chip clearance while maintaining rigidity in the tap body. The H3 thread limit designation indicates a controlled oversize tolerance appropriate for standard UNF threading work where fit and thread class matter.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in machine shop, maintenance, and light fabrication environments where 3\/4-16 UNF threaded holes are required. It is appropriate for right-hand thread cutting in through-hole applications in steel, aluminum, and similar machinable materials. Machinists, maintenance technicians, and skilled tradespeople working on mechanical assemblies, hydraulic fittings, and fastener repair will find this tap applicable to both new-thread creation and rethreading operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4-16 UNF thread size with right-hand thread direction for standard fastener compatibility\u003c\/li\u003e\n  \u003cli\u003eTaper chamfer distributes cutting load across the lead threads for smoother through-hole entry\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides hardness and wear resistance across a broad range of machinable workpiece materials\u003c\/li\u003e\n  \u003cli\u003eGold oxide coating reduces friction during cutting and offers moderate corrosion resistance during storage\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit ensures consistent oversize tolerance for standard UNF thread class fit\u003c\/li\u003e\n  \u003cli\u003e4-flute design balances chip evacuation and tap body strength\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard tooling option for applications requiring 3\/4-16 UNF straight flute taps with a taper chamfer and H3 thread limit.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap is intended for use by machinists and qualified tradespeople operating drill presses, tapping machines, or hand tapping setups. Always secure the workpiece firmly and use appropriate cutting fluid for the workpiece material to extend tap life and improve thread quality. Ensure the tap is aligned perpendicular to the workpiece surface before applying cutting pressure. Do not force a tap that has stalled — back off to break the chip before continuing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 16\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: H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Taper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003eWeight\u003c\/strong\u003e: 0.01 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: IMPORT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: BDNA-20779\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IMPORT-GENERIC","offers":[{"title":"Default Title","offer_id":51707787477298,"sku":"BDNA-20779","price":38.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/244503fb6f21a5b62deca537d3690e3c.jpg?v=1788442147","url":"https:\/\/voomisupply.com\/products\/import-bdna-20779-3-4-16-unf-straight-flute-tap-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
