Manufactured from high speed steel with a bright uncoated finish, this tap handles the demands of general-purpose threading in a shop or field environment. It covers a 1-5\/16-12 thread form to the UNS standard and features a right-hand thread direction. With 4 straight flutes and an H4 thread limit, it suits applications requiring consistent thread tolerance in steel, cast iron, aluminum, and similar materials.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in machining, maintenance, and fabrication settings where large-diameter UNS threads are required. The bottoming chamfer — typically 1 to 2 threads of lead — allows threading to the bottom of blind holes. It measures 5.75 inches overall length with a 1.5-inch thread length, making it appropriate for moderate-depth threading passes. Machinists, tool-and-die workers, and maintenance technicians in industrial and manufacturing environments are the primary users of this tap.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBottoming chamfer for threading to the base of blind holes\u003c\/li\u003e\n  \u003cli\u003e1-5\/16-12 UNS thread form, right-hand direction\u003c\/li\u003e\n  \u003cli\u003eH4 thread limit for controlled tolerance fit\u003c\/li\u003e\n  \u003cli\u003e4 straight flutes for chip clearance in through and blind hole applications\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides hardness and wear resistance\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no coating buildup to affect thread dimensions\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 1-5\/16-12 UNS bottoming hand tap with an H4 thread limit in a 4-flute straight flute configuration.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap is intended for use by machinists and maintenance technicians using a tap wrench or appropriate machine holder. Ensure the workpiece is securely clamped and the pilot hole is drilled to the correct tap drill diameter for a 1-5\/16-12 thread before beginning. Apply a suitable cutting fluid for the workpiece material to extend tool life and improve thread quality. Back the tap off periodically to break chips and avoid binding, particularly in blind holes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-5\/16-12\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: Bottoming\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: H4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\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: 5.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.5 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\u003ePackage Quantity\u003c\/strong\u003e: 1\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: JY4871091\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51721029615922,"sku":"JY4871091","price":184.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c13d11f8eb230b220a7c4ae7466d4132.jpg?v=1788572514","url":"https:\/\/voomisupply.com\/products\/value-collection-jy4871091-hand-tap-1-5-16-12-uns","provider":"Voomi Supply","version":"1.0","type":"link"}
