Built from high speed steel with a bright finish, this set delivers consistent thread quality across a range of ferrous and non-ferrous materials. The 4-flute geometry provides efficient chip evacuation and stable cutting action. With an overall length of 3-5\/32 inches and an H3 thread limit, the set holds tight tolerances suitable for precision fastener applications. Machinists, maintenance technicians, and tool-and-die professionals reach for this set when threading bolt holes, repair bores, or new component assemblies to UNF standard.\u003c\/p\u003e\n\u003cp\u003eThis tap set is suited for general machining and maintenance applications requiring a fine-thread 7\/16-20 UNF fit. The 3-piece configuration typically includes a taper, plug, and bottoming tap, covering through-hole and blind-hole threading scenarios. It is appropriate for use in job shops, production floors, and field maintenance environments where accurate fine-thread cutting in steel, aluminum, and similar materials is required. Class of fit 2B and 3B coverage makes it versatile for standard and close-tolerance assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7\/16-20 UNF thread size for fine-pitch fastener applications\u003c\/li\u003e\n  \u003cli\u003e4-flute design promotes chip clearance and cutting stability\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction withstands heat generated during threading\u003c\/li\u003e\n  \u003cli\u003eBright finish suitable for use with cutting fluids and oils\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit ensures consistent fit within UNF tolerance range\u003c\/li\u003e\n  \u003cli\u003eClass of fit 2B and 3B accommodates standard and close-tolerance thread requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for cutting 7\/16-20 UNF internal threads to 2B and 3B class of fit in compatible workpiece materials.

Secure the workpiece completely before beginning any threading operation and ensure the tap is aligned perpendicular to the bore. Do not force the tap if resistance increases suddenly, as this may indicate chip packing or material hardness beyond tool rating. Follow shop safety protocols and applicable workplace standards when operating drilling or tapping equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/16-20 UNF\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\u003eOverall Length\u003c\/strong\u003e: 3-5\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B, 3B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePieces\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.27 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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: K008928AS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51754413392178,"sku":"K008928AS","price":78.67,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/522b7775fbd2a188c6f6d67f379640b2.jpg?v=1788945149","url":"https:\/\/voomisupply.com\/products\/hertel-k008928as-tap-set-7-16-20-unf-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
