Built from high-speed steel with a bright uncoated finish, it cuts a 2-64 UNF right-hand thread to a 2B class of fit. The H2 thread limit ensures consistent dimensional tolerance across production runs. With a 7\/16 inch thread length and an overall length of 1-3\/4 inches, this tap is sized for small-fastener applications in light metals, plastics, and similar materials. It is a standard three-flute configuration with a plug chamfer, making it suitable for starting threads in a pre-drilled hole.\u003c\/p\u003e\u003cp\u003eThis tap is used in machining, fabrication, and assembly operations where 2-64 UNF threads are required. The plug chamfer provides a gradual thread start, which suits both hand tapping and machine tapping in drill press or CNC applications. Typical use cases include threading small clearance holes in instrument housings, electronics enclosures, optical mounts, and precision mechanical assemblies. Machinists, tool-and-die technicians, and precision fabricators are the primary users of this size range.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2-64 UNF thread form, right-hand, 2B class of fit for standard tolerance internal threads\u003c\/li\u003e\n\u003cli\u003eH2 thread limit for consistent fit across repeated use\u003c\/li\u003e\n\u003cli\u003eThree straight flutes with plug chamfer for gradual thread engagement\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for durability across a range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish — no coating buildup to affect tolerance in fine thread sizes\u003c\/li\u003e\n\u003cli\u003eCompact 1-3\/4 inch overall length suits confined workpiece geometries\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard OEM-style replacement or production tap for any application requiring a 2-64 UNF straight flute plug tap with a 2B class of fit and H2 thread limit.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is installed by machinists or precision fabricators using a tap wrench, tapping head, or CNC rigid tapping cycle. Always use the correct tap drill size for a 2-64 UNF thread before tapping, and apply appropriate cutting fluid for the workpiece material. Secure the workpiece firmly and align the tap perpendicular to the hole to avoid tap breakage, which is a significant risk at this small diameter. Back the tap out periodically to break and clear chips when hand tapping.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 2-64 UNF\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H2\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 Length\u003c\/strong\u003e: 7\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1410 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.1100 inches\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: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: K008049AS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51748830839090,"sku":"K008049AS","price":30.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/82a2cea270a0050939af649e56a45721.jpg?v=1788899174","url":"https:\/\/voomisupply.com\/products\/hertel-k008049as-straight-flute-tap-2-64-unf-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
