Built from high-speed steel with a bright\/uncoated finish, this tap delivers reliable performance in hand-tapping and machine-tapping operations where left-hand thread profiles are required. The plug chamfer — typically 3 to 5 threads — makes it suited for through-hole applications where the tap can enter and advance freely. With 4 flutes and an H4 thread limit, it holds close tolerances to meet 3B class of fit requirements in production and maintenance threading work.\u003c\/p\u003e\u003cp\u003eThis tap is used in applications where standard right-hand threads are not acceptable, including reverse-thread fastener assemblies, left-hand threaded spindles, and components subject to counterclockwise torque loads. The 1-14 UNS designation covers unified national special threads at a 1-inch nominal diameter with 14 threads per inch — a combination found in specialty mechanical assemblies across industrial, tooling, and heavy equipment environments. Machinists, tool and die makers, and maintenance technicians working in job shops or plant maintenance settings are the primary installers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand thread direction for reverse-thread applications\u003c\/li\u003e\n\u003cli\u003e1-14 UNS thread form at 14 threads per inch, 1-inch nominal diameter\u003c\/li\u003e\n\u003cli\u003ePlug chamfer for through-hole tapping with controlled lead-in\u003c\/li\u003e\n\u003cli\u003e4 straight flutes for chip clearance in short-chipping materials\u003c\/li\u003e\n\u003cli\u003eH4 thread limit for consistent 3B class of fit tolerances\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for strength and wear resistance at moderate cutting speeds\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish — suitable for use with cutting fluids across a range of materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use tap for threading 1-14 UNS left-hand holes in applications requiring 3B class of fit tolerances.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap should be installed and operated by qualified machinists or maintenance technicians familiar with threading operations. Always secure the workpiece fully and use the appropriate tapping fluid for the material being threaded. Back the tap off periodically to break chips and clear the flutes, especially in deeper holes. Do not force the tap — if resistance increases sharply, back out and clear chips before continuing to avoid breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-14\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 14\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer\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\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\u003eWeight\u003c\/strong\u003e: 1.24 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: JY4919148\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693881033010,"sku":"JY4919148","price":82.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/429ce87237063fd828b9ff6250a8a74c.jpg?v=1788318478","url":"https:\/\/voomisupply.com\/products\/value-collection-jy4919148-straight-flute-tap-1-14-uns","provider":"Voomi Supply","version":"1.0","type":"link"}
