Built from high speed steel with a bright uncoated finish, this tap delivers consistent thread cutting performance in both production and maintenance environments. The plug chamfer — typically 3 to 5 threads — provides a balance between starting ease and thread engagement depth, making it a general-purpose choice for through holes and deeper blind holes where a starting or bottoming tap is not required. The 6-flute configuration increases the number of cutting edges, improving thread quality and reducing chatter in harder materials. Installed by machinists and maintenance technicians using a standard tap wrench or machine tapping setup.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for threading operations in ferrous and non-ferrous metals, plastics, and similar machinable materials where a 1-5\/16-20 UNS thread form is specified. The UNS thread standard covers unified national special threads that fall outside the standard UNC and UNF series, making this tap appropriate for specialized fastener applications, repair work, and OEM production requiring this specific pitch. The right-hand thread direction is standard for conventional tapping. The 4-inch overall length provides adequate shank clearance for use in most tapping fixtures and CNC tapping arms.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-5\/16-20 UNS thread size with right-hand thread direction for standard tapping operations\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer provides 3 to 5 thread lead for versatile use in through holes and deeper blind holes\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction handles a broad range of machinable materials\u003c\/li\u003e\n  \u003cli\u003e6-flute design increases cutting edges for improved thread finish and reduced deflection\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no coating buildup to affect thread tolerance in close-tolerance applications\u003c\/li\u003e\n  \u003cli\u003eClass of fit 3B with H4 thread limit ensures accurate thread geometry for standard tolerance fits\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or production tap for applications requiring a 1-5\/16-20 UNS internal thread with a 3B class of fit and H4 thread limit.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eHand taps of this size should be installed by experienced machinists or maintenance technicians familiar with tapping operations. Always secure the workpiece and use a properly aligned tap wrench or tapping fixture to prevent tap breakage and thread distortion. Apply appropriate cutting fluid for the workpiece material to extend tap life and improve thread finish. Inspect the tap for wear or chipping before each use — a damaged cutting edge on a tap this size can be difficult to detect visually but will produce out-of-tolerance threads.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-5\/16-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\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\u003eFlute Style\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\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\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\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: JY4871208\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714371518770,"sku":"JY4871208","price":279.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e30789b926a4bbe24f0690f6366efc58.jpg?v=1788500425","url":"https:\/\/voomisupply.com\/products\/value-collection-jy4871208-hand-tap-1-5-16-20-uns-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
