Made from high-speed steel with a bright, uncoated finish, this tap is built for threading operations that require the thread to run close to the bottom of a blind hole. The bottoming chamfer provides minimal lead-in, allowing full thread engagement near the base of the bore. With 4 flutes and an H3 thread limit, it suits applications calling for a 3B class of fit. Overall length is 3-19\/32 inches, and thread direction is right hand.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for machinists, tool-and-die makers, and maintenance technicians working on precision threading jobs in ferrous and non-ferrous materials. The UNS (Unified National Special) 9\/16-28 thread form is used in specialized mechanical assemblies where standard thread pitches do not apply. The bottoming configuration makes it the correct choice when a plug or taper tap has already started the thread and full-depth threading to the bottom of a blind hole is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBottoming chamfer allows threading to the base of blind holes after pre-threading with a plug or taper tap\u003c\/li\u003e\n  \u003cli\u003e4-flute straight flute design provides rigidity and clean chip management in through and blind hole applications\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction offers durability across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit and 3B class of fit ensure consistent, standards-compliant thread tolerance\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish suits general-purpose threading without added coating friction considerations\u003c\/li\u003e\n  \u003cli\u003eRight hand thread direction for standard threading operations\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 9\/16-28 UNS bottoming tap with a 3B class of fit and H3 thread limit in straight flute configuration.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or maintenance technician using a tap wrench, tapping fixture, or machine spindle appropriate for the workpiece setup. Always ensure the hole is pre-drilled to the correct tap drill diameter for a 9\/16-28 UNS thread before beginning. Power down and secure the workpiece before tapping. Use cutting fluid appropriate for the workpiece material to reduce tool wear and improve thread finish.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 9\/16-28\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNS\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: Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 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\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\u003eOverall Length\u003c\/strong\u003e: 3-19\/32 inches\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\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: JY4845301\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51707442692402,"sku":"JY4845301","price":91.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d1170d362416058c4e88ba481b3b9f59.jpg?v=1788440344","url":"https:\/\/voomisupply.com\/products\/value-collection-jy4845301-straight-flute-tap-9-16-28-uns","provider":"Voomi Supply","version":"1.0","type":"link"}
