This tap is designed to cut internal threads in through-holes and moderately deep blind holes, producing clean 4-40 UNC threads in metal, plastic, and other machinable materials. The plug chamfer — typically 3 to 5 threads of taper — makes it the most common tap style for general-purpose threading work. At 0.04 pounds, it is a compact, lightweight tool suited for benchtop and field use by machinists, maintenance technicians, and trade professionals who need reliable hand-tapping capability in small-diameter fastener applications.\u003c\/p\u003e\n\u003cp\u003eThe HT-440-P-D is used wherever 4-40 UNC threaded holes are required, including electrical enclosures, HVAC control panels, instrumentation housings, and light mechanical assemblies. The 4-40 thread size is a standard in small-fastener applications across commercial and residential trade work. This tap is intended for hand-tapping operations using a standard tap wrench and is not designed for CNC or power-feed use without proper setup.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-40 UNC thread form for small-diameter fastener applications\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer profile suitable for through-holes and moderately deep blind holes\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel (HSS) construction for durability across metal and plastic workpieces\u003c\/li\u003e\n  \u003cli\u003eUSA manufactured\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.04 pounds — easy to carry in a service kit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard hand plug tap for any application requiring 4-40 UNC internal threads in machinable materials.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eUse with a properly sized tap wrench and apply cutting fluid to extend tool life and produce cleaner threads when tapping steel or aluminum. Pre-drill with the correct 4-40 tap drill size before tapping. Reverse the tap periodically during cutting to break chips and reduce the risk of binding or breakage. This tool is intended for hand operation — do not use in a power drill or impact driver without a dedicated tapping attachment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-40 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Style\u003c\/strong\u003e: Hand Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: USA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: EAGLE CUTTING TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: HT-440-P-D\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233984610610,"sku":"HT-440-P-D","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307622883.png?v=1780114031","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-ht-440-p-d-4-40-hss-hand-plug-tap","provider":"Voomi Supply","version":"1.0","type":"link"}
