Built from cobalt with a bright finish, this plug chamfer tap generates 5-40 UNC right-hand threads in through-hole applications. The H4 thread limit ensures dimensional control in close-tolerance work. At 1.938 inches overall length with a 0.141-inch shank diameter, it fits standard tap holders used across production and maintenance machining environments. Licensed machinists and tool-and-die professionals are the primary users for this type of tap.\u003c\/p\u003e\u003cp\u003eThis tap is suited for through-hole threading in a range of metallic workpiece materials including alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel. The plug chamfer (4 to 4.5 chamfered threads) makes it appropriate for starting in through-holes where the tap can engage progressively. The HY-PRO NRT series is built for applications where chip evacuation is a concern and where thread forming is preferred over cutting to produce stronger, work-hardened threads.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThread forming design produces no chips, reducing the need for chip evacuation in through-hole work\u003c\/li\u003e\n\u003cli\u003eCobalt construction provides heat resistance for tapping harder and more abrasive materials\u003c\/li\u003e\n\u003cli\u003ePlug chamfer (4 to 4.5 threads) allows progressive engagement in through-holes\u003c\/li\u003e\n\u003cli\u003eH4 thread limit maintains dimensional accuracy in close-tolerance threading\u003c\/li\u003e\n\u003cli\u003eRight-hand, 5-40 UNC thread form compatible with standard unified coarse thread specifications\u003c\/li\u003e\n\u003cli\u003eBright finish with no coolant-through requirement simplifies setup in standard tapping operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for through-hole threading in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces.

Use a cutting fluid or tapping lubricant appropriate for the workpiece material to reduce galling and extend tap life. Ensure the workpiece is securely fixtured and the tap is aligned perpendicular to the hole before engagement. Follow applicable shop safety procedures and machine tool manufacturer guidelines when setting spindle speed and feed rate.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5-40\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: 40\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: H4\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: 1.938 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.299 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 0.626 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.141 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.110 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.1875 inches\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: Alloy Steel, Aluminum, Carbon Steel, Die Steel, Hardened Steel, Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HY-PRO NRT (14001)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.005 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: 1400108400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51740195750194,"sku":"1400108400","price":35.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f9e0a7535aeb52c331c9ab34d6077839_d149692e-6be4-4b33-af1e-54de8c611080.jpg?v=1788823420","url":"https:\/\/voomisupply.com\/products\/osg-1400108400-thread-forming-tap-5-40-unc-plug-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
