Manufactured from high speed steel with a bright, uncoated finish, this tap offers durable cutting performance in general-purpose threading applications. The taper chamfer distributes cutting load across multiple leading threads, making it well-suited for starting threads in through-holes or blind holes with adequate depth. With six flutes and a 3B class of fit at H4 thread limit, it produces threads within standard tolerance for precision fastener assemblies. Overall length is 6-1\/16 inches with a 3-inch thread length. The tap weighs approximately 1.1 pounds.\u003c\/p\u003e\n\u003cp\u003eThis hand tap is used in metalworking and maintenance applications where 1-3\/8-12 UNF threads are required. The right-hand thread direction and taper chamfer make it appropriate for use with a tap wrench or threading fixture on ferrous and non-ferrous metals. Machinists, tool and die makers, and maintenance technicians working on industrial equipment, hydraulic fittings, or structural assemblies will find this tap applicable to a wide range of threading jobs requiring UNF coarse-pitch replacement or new-thread cutting.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-3\/8-12 UNF thread size with right-hand thread direction\u003c\/li\u003e\n  \u003cli\u003eTaper chamfer for gradual thread engagement and easier thread starting\u003c\/li\u003e\n  \u003cli\u003e6-flute straight-flute geometry for general-purpose threading in through and blind holes\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durable performance across a range of materials\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for use with standard cutting fluids\u003c\/li\u003e\n  \u003cli\u003e3B class of fit at H4 thread limit for standard-tolerance threaded assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard hand tap for cutting 1-3\/8-12 UNF internal threads.

Always secure the workpiece firmly and use an appropriate cutting fluid to reduce friction and extend tap life. Apply consistent, controlled torque with a properly sized tap wrench, backing off periodically to break chips. Inspect the tap for wear or chipping before each use to avoid thread damage or 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: 1-3\/8-12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Taper\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 Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6-1\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 3 inches\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\u003eWeight\u003c\/strong\u003e: 1.1 pounds\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: MSC-04489571\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51702851469618,"sku":"MSC-04489571","price":147.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3c5d5eeeb1607043dd0706c732098511.jpg?v=1788413534","url":"https:\/\/voomisupply.com\/products\/value-collection-msc-04489571-hand-tap-1-3-8-12-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
