Unlike cutting taps, thread forming taps displace material rather than cut it, producing stronger threads with no chips to clear. This tap is manufactured from powdered metal high-speed steel and carries a Titanium Nitride (TiN) coating for extended tool life and reduced friction during tapping. The plug chamfer style features 4 chamfered threads, making it suitable for through-hole applications where the tap can pass fully through the workpiece. Machinists and tool and die tradespeople working on fastener assemblies, fixture work, and precision components will find this tap appropriate for production and repair use.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for through-hole threading operations on ductile metals where cold-forming thread geometry is preferred over cutting. The 8-32 UNC thread size is a standard coarse-thread designation widely used in electrical enclosures, light mechanical assemblies, and instrumentation hardware. The right-hand thread direction and Class 2B fit make it compatible with standard UNC fastener assemblies. The plug chamfer allows the tap to start easily in a pre-drilled hole and follow through completely, which is the standard approach for through-hole work on production lines and bench setups alike.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread forming (cold-form) design displaces material for chip-free, stronger threads\u003c\/li\u003e\n  \u003cli\u003ePowdered metal high-speed steel construction for improved wear resistance over conventional HSS\u003c\/li\u003e\n  \u003cli\u003eTitanium Nitride (TiN) coating reduces friction and extends tool life\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer with 4 chamfered threads for through-hole threading applications\u003c\/li\u003e\n  \u003cli\u003eClass 2B fit with H5 thread limit for standard UNC fastener compatibility\u003c\/li\u003e\n  \u003cli\u003eSingle oil groove for lubrication during the forming process\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use thread forming tap for 8-32 UNC through-hole threading in ductile metal workpieces requiring a Class 2B, H5 thread limit fit.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThread forming taps require a proper tap drill size for the specific material being tapped — consult a thread forming drill chart before drilling the pilot hole, as the required drill diameter differs from cutting tap specifications. Use a suitable tapping fluid or cutting oil rated for the workpiece material to protect both the tap and the formed thread. Secure the workpiece firmly before tapping and maintain axial alignment throughout to avoid tap breakage. This tool is intended for use by machinists and qualified tradespeople familiar with hand or machine tapping procedures.\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\u003eChamfer\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 4P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Powdered Metal High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Through-Hole Threading\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: 0.470 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 0.750 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\u003eOil Grooves\u003c\/strong\u003e: 1\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: 0.1 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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 11645-00T\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730430066994,"sku":"11645-00T","price":46.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2dba84c7824878f80380341588dfc38c.jpg?v=1788717318","url":"https:\/\/voomisupply.com\/products\/accupro-11645-00t-thread-forming-tap-8-32-unc-plug-tin-coated","provider":"Voomi Supply","version":"1.0","type":"link"}
