The plug chamfer — typically 3 to 5 threads of lead — makes this tap suitable for through-holes and moderately deep blind holes where thread engagement needs to start cleanly. HSS construction provides the hardness and wear resistance required for production tapping in a range of base materials. Machinists, maintenance technicians, and tool-and-die professionals reach for this style of tap when hand-threading or when running a low-speed tapping head.\u003c\/p\u003e\u003cp\u003eThe HT-440-P-I is used in light manufacturing, maintenance and repair operations (MRO), and general fabrication settings where 4-40 UNC threaded fasteners are common. Typical applications include threading holes in aluminum, mild steel, brass, and similar machinable materials. The hand tap designation indicates it is intended for manual operation with a tap wrench, though it can also be used in slow-speed machine tapping setups with appropriate toolholding.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-40 UNC thread form for standard inch-series fastener compatibility\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel (HSS) construction for hardness and extended tool life\u003c\/li\u003e\n\u003cli\u003ePlug chamfer profile suitable for through-holes and moderately deep blind holes\u003c\/li\u003e\n\u003cli\u003eHand tap design compatible with standard tap wrenches and low-speed tapping setups\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.31 pounds for easy single-hand operation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 4-40 UNC hand plug tap suitable for use with any tap wrench or manual tapping fixture accepting the appropriate square-drive shank size for this thread class.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSecure the workpiece firmly before tapping and ensure the tap is started square to the hole to prevent thread misalignment or tap breakage. Use an appropriate cutting fluid for the base material being threaded. Back the tap off periodically to break chips, especially in blind holes. Always wear appropriate eye protection when performing tapping operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-40 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTap Type\u003c\/strong\u003e: Hand Plug Tap\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.31 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: EAGLE CUTTING TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: HT-440-P-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233740030258,"sku":"HT-440-P-I","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307622890.png?v=1780107972","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-ht-440-p-i-4-40-hss-hand-plug-tap","provider":"Voomi Supply","version":"1.0","type":"link"}
