Unlike cut taps, thread forming taps displace material rather than removing chips, producing stronger threads with improved surface finish. This tap is ground to an H5 thread limit and features a plug chamfer with 4 to 4.5 chamfered threads for controlled thread entry. Built from cobalt high-speed steel with a bright finish, it handles demanding materials at elevated temperatures. The overall length is 3.156 inches, with a tapping depth of 1.713 inches and a shank diameter of 0.323 inches. Machinists and tool-and-die professionals are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis tap is configured for 7\/16-14 UNC right-hand threads and is suited for through-hole threading applications. It performs across a broad range of workpiece materials including alloy steel, carbon steel, die steel, hardened steel, stainless steel, and aluminum. The plug chamfer makes it appropriate for through-hole work where the tap can pass completely through the part. It is well suited for production machining, maintenance, and toolroom environments where thread strength and dimensional accuracy are critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread forming design displaces material for stronger, chip-free internal threads\u003c\/li\u003e\n  \u003cli\u003eCobalt construction provides heat resistance for hard and stainless steel applications\u003c\/li\u003e\n  \u003cli\u003eH5 thread limit ensures consistent tolerance control on 7\/16-14 UNC threads\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer with 4 to 4.5 chamfered threads optimized for through-hole threading\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, compatible with standard tapping equipment and CNC setups\u003c\/li\u003e\n  \u003cli\u003eBright finish with no coolant-through requirement simplifies setup\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for through-hole threading in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces.

Adequate lubrication or tapping fluid is essential, particularly in stainless and alloy steel, to reduce forming torque and prevent tap breakage. Ensure the workpiece is securely fixtured and the tap is properly aligned to the spindle axis before engagement. Follow all applicable shop safety procedures and machine guarding requirements when tapping operations are underway.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/16-14\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 14\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 4 to 4.5P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Through-Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.156 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.858 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 1.713 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: 0.406 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HY-PRO NRT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.155 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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1400140100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51731738329394,"sku":"1400140100","price":64.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f9e0a7535aeb52c331c9ab34d6077839_4053efe0-49a5-4c33-942c-83f5a8b9810c.jpg?v=1788734392","url":"https:\/\/voomisupply.com\/products\/osg-1400140100-thread-forming-tap-7-16-14-unc-plug-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
