Built from high-speed steel with a bright, uncoated finish, it produces a 7\/16-14 UNC right-hand thread. The plug chamfer provides a moderate lead-in of 3 to 5 threads, making it suitable for through-hole and moderately deep blind-hole applications. With 4 flutes and an H5 thread limit, the 1141900 delivers consistent thread tolerance control in production and maintenance machining environments. It measures 3-5\/32 inches overall with a 1-7\/16 inch thread length, and it does not require coolant-through capability.\u003c\/p\u003e\u003cp\u003eThis tap is intended for use in manual, CNC, and turret machine tapping setups. It is well-suited to tapping aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, and high-carbon steel. The 7\/16-14 UNC thread form is a common fastener standard found in structural, mechanical, and fabrication work across commercial and industrial applications. Machinists, tool and die makers, and maintenance technicians regularly specify this tap for general-purpose threading tasks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7\/16-14 UNC thread form with right-hand cut for standard fastener applications\u003c\/li\u003e\n\u003cli\u003ePlug chamfer style for use in through-holes and shallow blind holes\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction provides durability across a broad material range\u003c\/li\u003e\n\u003cli\u003eH5 thread limit for consistent tolerance control in production threading\u003c\/li\u003e\n\u003cli\u003e4 straight flutes for chip control in shorter-chip materials such as cast iron and aluminum\u003c\/li\u003e\n\u003cli\u003eNo coolant-through requirement simplifies setup on standard machine configurations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard OEM-style straight flute tap compatible with 7\/16-14 UNC threading applications in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, and high-carbon steel workpieces.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists familiar with tapping speeds, feeds, and cutting fluid requirements for the specific workpiece material. Always secure the workpiece and verify spindle alignment before engaging the tap. Back the tap out periodically to clear chips and prevent binding, particularly in deeper holes. Follow applicable shop safety practices and machine manufacturer guidelines for tapping operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/16-14 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 14\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003eThread Limit\u003c\/strong\u003e: H5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1-7\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-5\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.323 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.242 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.40625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 1.689 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\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Cast Aluminum, Cast Iron, Low-Carbon Steel, Medium-Carbon Steel, High-Carbon Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 101\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.075 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1141900\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51742391304498,"sku":"1141900","price":39.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/326d7ab8b02d8071a42bd324ef4f1ff7_7ff29d78-6c0d-47d1-a2e1-19473a05b4f6.jpg?v=1788837164","url":"https:\/\/voomisupply.com\/products\/osg-1141900-straight-flute-tap-7-16-14-unc-plug-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
