Built from high speed steel (HSS) with a bright, uncoated finish, this tap is suited for general-purpose threading in a wide range of workpiece materials. It cuts a 1\/4-28 UNF right-hand thread and features 2 flutes that push chips forward ahead of the cut, reducing clogging in through-hole work. The H11 thread limit indicates a slightly oversize ground tolerance, accommodating plated or coated threads where the finished hole requires a tighter fit after post-processing.\u003c\/p\u003e\u003cp\u003eThis tap is used in manufacturing, maintenance, and repair applications wherever a 1\/4-28 UNF thread is required in through-hole configurations. The plug chamfer — typically 3 to 5 threads of lead — makes it the standard choice for general threading where the tool can pass fully through the material. It is appropriate for use in hand tapping or low-speed machine tapping setups. Machinists, tool-and-die technicians, and maintenance professionals regularly use this type of tap for fastener repair and fabrication work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-28 UNF right-hand thread form for standard unified fine thread applications\u003c\/li\u003e\n\u003cli\u003e2-flute spiral point design pushes chips forward, ideal for through-hole threading\u003c\/li\u003e\n\u003cli\u003ePlug chamfer provides a moderate lead for easy thread starting in most applications\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction offers durability across a broad range of common materials\u003c\/li\u003e\n\u003cli\u003eH11 thread limit ground oversize at 0.0050 inches to allow for plating or coating after threading\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for use with standard cutting fluids\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or general-use spiral point tap for any application requiring a 1\/4-28 UNF right-hand internal thread in through-hole workpieces.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap should be installed in a tap wrench or machine tap holder appropriate for the shank size before use. Always apply a suitable cutting fluid for the workpiece material to reduce friction and extend tool life. Ensure the workpiece is secured and the tap is aligned square to the hole before beginning the threading operation. Reverse the tap periodically when hand tapping to break chips and prevent tap breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-28\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H11\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOversize\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmount Oversize\u003c\/strong\u003e: 0.0050 inches\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: 0.0017 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: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: JY8962615\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690500129074,"sku":"JY8962615","price":16.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/89229f57acb70d6e543c5534704d4991.jpg?v=1788270634","url":"https:\/\/voomisupply.com\/products\/value-collection-jy8962615-1-4-28-unf-spiral-point-tap-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
