Built from high speed steel (HSS) with a bright finish, this set delivers consistent thread formation across a range of material hardnesses. The 4-flute geometry provides efficient chip evacuation and stable cutting action. Overall length is 2-23\/32 inches, and the set covers both 2B and 3B class of fit applications, making it suitable for standard and close-tolerance threaded assemblies. Machinists, maintenance technicians, and tool-and-die professionals rely on this type of tap set for production and repair threading operations.\u003c\/p\u003e\n\u003cp\u003eThis tap set is suited for threading operations in light manufacturing, machine shops, and maintenance environments where 5\/16-18 UNC thread profiles are required. The H3 thread limit designation makes it appropriate for plated or close-tolerance fit applications. The 3-piece set typically includes a taper, plug, and bottoming tap, allowing complete through-hole and blind-hole threading in a single kit. It is well matched to hand tapping and low-speed machine tapping setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC thread profile for standard fractional fastener applications\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003e4-flute design for stable cutting and effective chip removal\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit supports plated and close-tolerance fit requirements\u003c\/li\u003e\n  \u003cli\u003eCovers 2B and 3B class of fit in a single set\u003c\/li\u003e\n  \u003cli\u003eBright finish, uncoated — suitable for use with cutting fluid\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for cutting 5\/16-18 UNC internal threads; compatible with standard 5\/16-18 UNC fastener assemblies requiring 2B or 3B class of fit.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eTap installation should be performed by a qualified machinist or maintenance technician. Always secure the workpiece firmly and use appropriate cutting fluid to extend tool life and improve thread quality. For hand tapping, use a calibrated tap wrench and advance in reverse periodically to break chips. For machine tapping, verify spindle speed and feed rate are appropriate for the workpiece material before starting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18 UNC\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: 2-23\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H3\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 Included\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.16 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: K008923AS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51744969589042,"sku":"K008923AS","price":47.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4be4e0659b4e6adfa98f918ba715b08c.jpg?v=1788862812","url":"https:\/\/voomisupply.com\/products\/hertel-k008923as-tap-set-5-16-18-unc-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
