Plug taps feature a tapered lead of roughly 3 to 5 threads, making them the standard starting choice when threading through holes or when sufficient thread engagement allows a gradual entry. This tap is designed for cutting internal threads by hand in materials such as mild steel, aluminum, brass, and plastics. Machinists, tool-and-die technicians, and maintenance professionals reach for this tap when precision thread quality and tool longevity are the priority over disposable import tooling.\u003c\/p\u003e\n\u003cp\u003eThe HT-540-P-D cuts a 5-40 Unified National Coarse (UNC) thread profile, which is common in small fastener applications across electronics, instrumentation, precision assemblies, and light mechanical components. It is suited for use in job shops, maintenance facilities, and production environments where hand tapping small-diameter threads is a regular task. This tap is driven with a standard tap wrench and is appropriate for both new thread cutting and thread repair applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5-40 UNC thread form for small-diameter internal thread cutting\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer with 3 to 5 thread lead for versatile use in through holes and deeper blind holes\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel (HSS) construction for extended tool life versus carbon steel taps\u003c\/li\u003e\n  \u003cli\u003eUSA manufactured for consistent geometry and thread accuracy\u003c\/li\u003e\n  \u003cli\u003eMinimum order quantity of 1 — available as a single unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard hand plug tap for use wherever a 5-40 UNC internal thread is required.

Secure the workpiece firmly before tapping and apply cutting fluid appropriate to the workpiece material to extend tool life and improve thread finish. Back off the tap periodically to break chips and prevent binding, especially in blind holes. Inspect the tap for chipping or wear before each use, as small-diameter taps are susceptible to breakage under side load or overforce.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5-40 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Type\u003c\/strong\u003e: Hand Plug Tap\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-540-P-D\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233297662258,"sku":"HT-540-P-D","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307623019.png?v=1780096633","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-ht-540-p-d-5-40-hss-hand-plug-tap","provider":"Voomi Supply","version":"1.0","type":"link"}
