It is designed to cut internal threads by hand in a range of materials including steel, aluminum, and plastics. The plug chamfer — typically 3 to 5 threads — makes this tap suitable for through-holes and most general-purpose threading applications. Machinists, maintenance technicians, and trade professionals use plug taps as the standard starting choice when threading holes that have clear exit paths on both sides. At 0.08 pounds, it is a compact, lightweight tool sized for 6-40 unified fine (UNF) thread work.\u003c\/p\u003e\n\u003cp\u003eThis tap is used wherever 6-40 UNF internal threads are required, including light mechanical assemblies, instrument panels, electrical enclosures, and small fastener applications common in HVAC controls, electrical work, and general fabrication. The 6-40 thread designation indicates a No. 6 screw diameter with 40 threads per inch, a fine-thread pitch frequently encountered in precision and light-duty fastening scenarios. It is suited for bench work and hand-tapping operations in shop, field, and maintenance environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e6-40 UNF thread profile for fine-pitch internal threading\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel (HSS) construction provides hardness and wear resistance across a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer style accommodates through-hole threading and general-purpose hand tapping\u003c\/li\u003e\n  \u003cli\u003eUSA manufactured for consistent dimensional accuracy and thread form\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.08 pounds, easy to handle in confined spaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for hand tapping applications requiring 6-40 UNF internal threads.

Secure the workpiece firmly before starting, ensure the tap enters the hole square to the surface, and apply a suitable cutting fluid appropriate for the workpiece material. Back off periodically to break chips and prevent tap breakage. Worn or broken taps should be replaced rather than forced.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 6-40 UNF\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: 0.08 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-640-P-D\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233849573682,"sku":"HT-640-P-D","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307623087.png?v=1780110163","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-ht-640-p-d-6-40-hss-hand-plug-tap","provider":"Voomi Supply","version":"1.0","type":"link"}
