Built from high-speed steel (HSS), this tap is sized for 1\/4-20 UNC threads and features an H3 tolerance class, which accommodates standard plated and close-tolerance thread fits. With four flutes, it provides adequate chip clearance for use in a range of workpiece materials including mild steel, aluminum, and similar machinable metals. Machinists, maintenance technicians, and tool-and-die professionals reach for plug taps as the go-to starting point for most general tapping tasks.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for hand tapping operations in production and maintenance environments. The plug chamfer — typically 3 to 5 thread leads — allows the tap to start easily and progress smoothly into the workpiece. It is appropriate for use in ferrous and non-ferrous metals, plastics, and composites where a 1\/4-20 UNC thread form is required. Package quantity is one tap per unit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 UNC thread form for standard inch-series internal threading\u003c\/li\u003e\n  \u003cli\u003eH3 tolerance class for general-purpose and close-tolerance thread fits\u003c\/li\u003e\n  \u003cli\u003e4-flute straight flute geometry channels chips back through the flute in through-hole applications\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel (HSS) construction provides good wear resistance across a range of materials\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer style for easy starting in most hand tapping scenarios\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose straight flute hand plug tap compatible with standard 1\/4-20 UNC tapping applications in hand tapping and machine tapping setups that accept standard tap shank sizes.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eHand tapping should be performed with an appropriate tap wrench and cutting fluid suited to the workpiece material to reduce heat and extend tap life. Secure the workpiece firmly before starting and ensure the tap enters the hole square to the surface. Reverse the tap periodically to break chips and prevent binding. Broken taps are difficult to remove — never force a tap that feels locked in the hole.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Class\u003c\/strong\u003e: H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Straight\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\u003eWeight\u003c\/strong\u003e: 0.38 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 20A116CP\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699775701298,"sku":"20A116CP","price":33.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_d5e38d0f-8347-4f11-be3d-4fdc5356ef5c.jpg?v=1788380784","url":"https:\/\/voomisupply.com\/products\/value-collection-20a116cp-1-4-20-unc-h3-4fl-hss-hand-plug-tap","provider":"Voomi Supply","version":"1.0","type":"link"}
