Built from high-speed steel with a bright, uncoated finish, this tap features 4 flutes and a taper chamfer that guides the tool into the workpiece gradually, reducing the force required to start the cut. The H3 thread limit provides a controlled oversize condition suited to 2B and 3B class-of-fit applications. With an overall length of 2.375 inches and a thread length of 0.9375 inches, it fits standard tap handles and machine setups used in machining and fabrication environments.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for threading operations in job shops, maintenance and repair facilities, and light manufacturing settings. The taper chamfer makes it appropriate for through-hole applications where the tap can advance fully through the workpiece. The 12-28 UNF thread size is commonly encountered in fastener applications requiring a finer pitch than the standard UNC series, including instrument panels, brackets, and precision assemblies. Machinists, tool-and-die makers, and maintenance technicians are the primary users of this tool.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e12-28 UNF right-hand thread for fine-pitch internal threading\u003c\/li\u003e\n  \u003cli\u003eTaper chamfer for gradual engagement and easier thread starting\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for durability across common workpiece materials\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit supports 2B and 3B class-of-fit tolerances\u003c\/li\u003e\n  \u003cli\u003e4-flute straight design for chip clearance in through-hole applications\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for general-purpose use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose replacement or addition for standard tap-and-die sets and machine tapping operations requiring a 12-28 UNF straight flute taper tap.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap is installed by machinists using a standard tap handle or machine tap holder. Ensure the workpiece is securely clamped and the pilot hole is drilled to the correct tap drill size for 12-28 UNF before tapping. Apply cutting fluid appropriate for the workpiece material to extend tool life and improve thread quality. Inspect the tap for wear or chipping before each use and do not force a worn or damaged tap.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 12-28 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Taper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B, 3B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H3\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: 0.9375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.375 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: 0.06 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MSC-04439303\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692103074098,"sku":"MSC-04439303","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1d311b18a3799988cbf0842443d03b4f.jpg?v=1788293142","url":"https:\/\/voomisupply.com\/products\/value-collection-msc-04439303-straight-flute-tap-12-28-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
