Built from high speed steel (HSS) with a bright uncoated finish, this tap delivers reliable performance in general-purpose threading applications. The plug chamfer style — with a standard lead-in of roughly 3 to 5 threads — makes it suitable for through-holes and blind holes where adequate thread clearance is available. With 6 flutes and a 3B class of fit at an H4 thread limit, it produces precise, consistent threads that meet UNS tolerance standards. Right-hand thread direction applies. Overall length is 4 inches.\u003c\/p\u003e\n\u003cp\u003eThis hand tap is intended for use in machine shop, maintenance, and production environments where 1-1\/2-20 UNS internal threads are required. It is well-suited for manual tapping operations using a tap handle or tapping attachment, and is appropriate for threading steel, cast iron, aluminum, and similar workpiece materials. Machinists, tool and die makers, and maintenance technicians typically select this tap for repair threading and new-hole threading tasks in industrial and manufacturing settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/2-20 UNS thread specification for unified national special applications\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability in a wide range of materials\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — ready for use as supplied, no coating to chip or flake\u003c\/li\u003e\n  \u003cli\u003e6-flute straight-flute design promotes chip control and thread quality\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer for versatile use in through-holes and accessible blind holes\u003c\/li\u003e\n  \u003cli\u003e3B class of fit with H4 thread limit ensures consistent, tolerance-conforming threads\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use hand tap for any application requiring a right-hand 1-1\/2-20 UNS internal thread in standard 3B fit tolerance.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap is installed by machinists and maintenance technicians using a properly sized tap handle or tapping wrench. Always secure the workpiece before tapping and ensure the tap is started square to the hole to prevent breakage or thread misalignment. Apply appropriate cutting fluid for the workpiece material to extend tap life and improve thread finish. Never force a tap — back off periodically to break chips, especially in deeper holes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-1\/2-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\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\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\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: 4 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: JY4874202\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720759279922,"sku":"JY4874202","price":299.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e7278288b4de1c9d135fad72aba061d7.jpg?v=1788568744","url":"https:\/\/voomisupply.com\/products\/value-collection-jy4874202-hand-tap-1-1-2-20-uns-plug-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
