Built from cobalt high-speed steel with a bright finish, this plug-style tap carries a H10 thread limit and is configured for right-hand threading at 8-32 UNC. It measures 2.125 inches in overall length with a shank diameter of 0.168 inches and a tapping depth of 0.752 inches. Part of the HY-PRO NRT series, it is suited for production and maintenance threading in a wide range of metalworking environments.\u003c\/p\u003e\n\u003cp\u003eThis tap is engineered for through-hole threading applications across multiple material groups. It handles alloy steel, carbon steel, die steel, hardened steel, stainless steel, and aluminum. The plug chamfer with 4 to 4.5 chamfered threads makes it appropriate for starting in a pre-drilled hole and continuing through the full depth. It is used in manufacturing, toolroom, and mechanical assembly settings where formed threads are preferred over cut threads for improved fatigue resistance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt high-speed steel construction for improved heat and wear resistance in tough materials\u003c\/li\u003e\n  \u003cli\u003eThread forming (chipless) design produces stronger threads by cold-working the material\u003c\/li\u003e\n  \u003cli\u003eH10 thread limit for precise tolerance control on 8-32 UNC threads\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer (4 to 4.5 threads) for easy starting in through-hole applications\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, compatible with standard tapping equipment\u003c\/li\u003e\n  \u003cli\u003eBright finish with no coating for straightforward inspection and regrinding\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct tooling option for 8-32 UNC through-hole thread forming operations in alloy steel, carbon steel, die steel, hardened steel, stainless steel, and aluminum workpieces.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThread forming taps require a correctly sized forming tap drill — not a standard tap drill — to achieve the proper minor diameter before tapping. A machinist or toolroom technician should ensure the spindle speed and lubricant are appropriate for the workpiece material, as thread forming generates more torque than cutting taps. Do not reverse the tap under power without confirming the machine and holder support it. Secure the workpiece fully before beginning the tapping cycle.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 8-32\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: 32\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Style\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 4 to 4.5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt High-Speed Steel\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: 2.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.374 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 0.752 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.168 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.131 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Through-Hole Threading\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\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: 0.02 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: 1400115900\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51737891406130,"sku":"1400115900","price":30.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2fe8e744a7ca476e0244fdcdf42e2e4c.jpg?v=1788794889","url":"https:\/\/voomisupply.com\/products\/osg-1400115900-thread-forming-tap-8-32-unc-plug-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
