Built from high-speed steel (HSS) and finished with a gold oxide coating, this tap offers improved lubricity and resistance to heat buildup during cutting operations. It features 3 flutes and a plug chamfer, which provides a gradual lead-in that works well for through holes and moderately deep blind holes. The overall length is 1-7\/8 inches and the tap is ground to an H2 thread limit for consistent, close-tolerance threading. Right-hand thread direction is standard.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for light machine work, general metalworking, and maintenance or repair threading applications where 4-40 UNC fasteners are used. It is appropriate for use in manual tap handles, T-handle wrenches, or machine tapping setups. Typical materials include aluminum, mild steel, brass, and similar machinable metals. At 40 threads per inch on a No. 4 diameter, this is a fine-pitched thread commonly found in electronics enclosures, instrument panels, and small mechanical assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-40 UNC thread form, 40 threads per inch on a No. 4 major diameter\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer provides gradual thread engagement, suitable for through holes and moderate blind holes\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction handles a broad range of machinable metals\u003c\/li\u003e\n  \u003cli\u003eGold oxide coating reduces friction and helps extend tool life\u003c\/li\u003e\n  \u003cli\u003eH2 thread limit ensures close-tolerance thread production\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, 3 flutes, 1-7\/8 inches overall length\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or general-use plug tap for any application requiring 4-40 UNC internal threads cut with a straight flute hand or machine tap.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThreading operations should be performed by a qualified machinist or technician familiar with proper tap alignment and cutting technique. Always secure the workpiece firmly before tapping and use an appropriate cutting fluid for the material being threaded to prevent tap breakage. Back the tap out periodically to clear chips, especially in deeper holes. Inspect the tap for wear or chipping before each use, as a damaged tap can produce out-of-tolerance threads or seize in the workpiece.\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Gold Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: IMPORT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: BDNA-20700\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IMPORT-GENERIC","offers":[{"title":"Default Title","offer_id":51693737967922,"sku":"BDNA-20700","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3220787e2fac9d4b6220686ccbc065e8.jpg?v=1788316752","url":"https:\/\/voomisupply.com\/products\/import-bdna-20700-straight-flute-tap-4-40-unc-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
