Built from high-speed steel with a bright, uncoated finish, this tap cuts a 2-1\/2-8 UNS right-hand thread profile to a thread limit of H6, offering controlled fit tolerance suitable for standard fastener assemblies. The plug chamfer  -  typically 3 to 5 threads of lead  -  makes it appropriate for starting in a hole or continuing after a taper tap in a sequential tapping operation. Machinists and maintenance technicians working on large-diameter threading jobs install this tap in manual tap handles or machine setups where torque requirements are managed carefully.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for threading large-diameter holes in ferrous and non-ferrous workpieces in industrial, maintenance, and fabrication environments. The 6-flute configuration provides more cutting edges than a standard 4-flute tap, distributing cutting load across the full thread engagement and improving surface finish in the cut thread. With a 4-inch thread length and an overall length of 8.75 inches, the JY4884029 handles thick stock or deep-reach applications where additional clearance above the workpiece is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2-1\/2-8 UNS thread form, right-hand cut, H6 thread limit for controlled tolerance fit\u003c\/li\u003e\n  \u003cli\u003e6 straight flutes distribute cutting load and improve thread finish\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer accommodates both through-hole and shallow blind-hole applications\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides wear resistance across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish  -  no added coating variables, ready for use with cutting fluid\u003c\/li\u003e\n  \u003cli\u003e4-inch thread length and 8.75-inch overall length support deep-reach and thick-stock threading\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use tap for applications requiring a 2-1\/2-8 UNS straight flute plug tap in high-speed steel.

Always secure the workpiece and use appropriate cutting fluid to reduce friction and heat buildup during the tapping operation. Do not force the tap  -  back off periodically to break chips and prevent tap breakage, especially in blind or deep holes. Inspect the tap for wear before each use; a worn or dull tap in a large-diameter application can result in damaged threads or a broken tool that is difficult to extract.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 2-1\/2-8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Type\u003c\/strong\u003e: Standard Straight Flute\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 8.75 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\u003eOversize\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 8.2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\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: JY4884029\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":67988948582706,"sku":"JY4884029","price":775.4,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/22e4b8e8b36e097c27087f04a98124ef.jpg?v=1792303000","url":"https:\/\/voomisupply.com\/products\/value-collection-jy4884029-straight-flute-tap-2-1-2-8-uns","provider":"Voomi Supply","version":"1.0","type":"link"}
