Built from high-speed steel with a bright\/uncoated finish, this tap handles 1-16 UNS threading with a plug chamfer that provides a gradual lead-in of approximately 3 to 5 threads. With 4 flutes and an H4 thread limit, it is suited for producing 3B class of fit threads in a range of workpiece materials. At 5.125 inches overall length, it fits standard tap wrenches and machine holders used in production and maintenance environments. Machinists, toolmakers, and maintenance technicians are the primary users of this tap.\u003c\/p\u003e\n\u003cp\u003eThis tap is applied in situations where a 1-16 UNS internal thread is required in metalworking, industrial fabrication, or equipment repair. The 1-16 UNS designation is an Unified National Special thread, used when standard coarse or fine pitch threads do not meet the design requirement. The plug chamfer makes this tap appropriate for starting in a pre-drilled hole and cutting to depth in through-hole applications. The right-hand thread direction matches the standard cutting orientation for most tapping operations by hand or machine.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-16 UNS thread form for specialized unified national special threading requirements\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer provides a 3 to 5 thread lead-in for smooth starting in pre-drilled holes\u003c\/li\u003e\n  \u003cli\u003e4-flute design channels chips and supports accurate thread form during cutting\u003c\/li\u003e\n  \u003cli\u003eH4 thread limit maintains 3B class of fit tolerances for standard internal thread assemblies\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides durability across a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish allows direct inspection of tool condition and wear\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard tooling option for any application requiring a 1-16 UNS, 3B class of fit internal thread in through-hole or open blind-hole configurations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap is installed and used by machinists and maintenance technicians in manual or machine tapping operations. Always secure the workpiece and ensure the pilot hole diameter matches the recommended tap drill size for 1-16 UNS before starting. Apply appropriate cutting fluid to extend tool life and improve thread quality. Reverse the tap periodically during hand tapping to break chips and prevent tap breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-16\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 Type\u003c\/strong\u003e: Plug\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: H4\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: 5.125 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  \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: JY4849147\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696707141938,"sku":"JY4849147","price":137.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c03d72f7427a792559a4c65dbcf54a3a.jpg?v=1788345431","url":"https:\/\/voomisupply.com\/products\/value-collection-jy4849147-straight-flute-tap-1-16-uns","provider":"Voomi Supply","version":"1.0","type":"link"}
