Built from high-speed steel with a bright uncoated finish, this tap produces 7\/16-20 UNF threads to a 3B class of fit, making it suitable for applications that require standard tolerance threaded connections. The H3 thread limit designation ensures consistent oversize compensation for plated or close-tolerance work. At 6 inches overall length, the extended reach allows threading in recessed or deep-cavity locations that standard-length taps cannot access. Machinists, maintenance technicians, and toolroom personnel will find this tap well suited for production and repair threading operations.\u003c\/p\u003e\u003cp\u003eThis extension tap is appropriate for use in ferrous and non-ferrous materials where 7\/16-20 UNF through-hole threading is required. The spiral point geometry pushes chips ahead of the tap and out of the hole, making it effective in through-hole applications on manual drill presses, CNC machining centers, and tapping machines. The reduced shank design allows the tap to seat in standard tap holders or chucks with smaller collet diameters. Typical applications include repair threading in machine frames, fixtures, and assemblies where extended reach is necessary.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSpiral point flute geometry pushes chips forward for efficient through-hole threading\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction provides hardness and wear resistance across common workpiece materials\u003c\/li\u003e\n\u003cli\u003e6-inch overall length extends reach into recessed bores and deep cavities\u003c\/li\u003e\n\u003cli\u003eH3 thread limit maintains tolerance for close-fit and post-plating applications\u003c\/li\u003e\n\u003cli\u003eReduced shank accommodates standard tap holders and smaller-bore chucks\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 an OEM-style replacement or direct-use tap for any application requiring 7\/16-20 UNF right-hand internal threads in through-hole configurations with a 3B class of fit.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or maintenance technician familiar with tapping procedures and cutting fluid requirements. Always secure the workpiece and ensure proper alignment before beginning the threading operation to avoid tap breakage. Use an appropriate cutting or tapping fluid for the workpiece material, and back the tap off periodically to clear chips when working in tougher alloys. Follow applicable shop safety standards and machine guarding requirements when operating tapping equipment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/16-20\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\u003eThread Limit\u003c\/strong\u003e: H3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 3B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTap Type\u003c\/strong\u003e: Spiral Point\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: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReduced Shank\u003c\/strong\u003e: Yes\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\u003eWeight\u003c\/strong\u003e: 0.9 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\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: JY4703203\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692555043122,"sku":"JY4703203","price":59.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3321b1c68dff88632ab5cc918468dba9.jpg?v=1788299211","url":"https:\/\/voomisupply.com\/products\/value-collection-jy4703203-extension-tap-7-16-20-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
