Built from high-speed steel (HSS) with a gold oxide coating, this tap is suited for general-purpose threading in a range of ferrous and non-ferrous materials. It cuts a 3\/8-16 UNC thread profile with 4 flutes and carries an H3 thread limit, which controls the tolerance class of the finished thread. Overall length is 2-15\/16 inches. Machinists, maintenance technicians, and trade professionals use this tap for field repairs, production threading, and replacement fastener work across industrial and mechanical applications.\u003c\/p\u003e\u003cp\u003eThis tap is appropriate for hand tapping or machine tapping operations where a standard plug chamfer is suitable. The plug chamfer style — typically 3 to 5 threads of taper — makes it versatile for starting threads in through-holes and for chasing existing 3\/8-16 UNC threads. It is commonly used in HVAC equipment assembly, electrical enclosure fabrication, plumbing fixture mounting, and general mechanical maintenance where unified coarse thread fasteners are standard.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/8-16 UNC thread form — unified coarse standard for broad fastener compatibility\u003c\/li\u003e\n\u003cli\u003e4 straight flutes for efficient chip evacuation in through-hole applications\u003c\/li\u003e\n\u003cli\u003ePlug chamfer style for versatile starting in through-holes and blind holes\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for durability across a range of materials\u003c\/li\u003e\n\u003cli\u003eGold oxide coating reduces friction and provides moderate corrosion resistance\u003c\/li\u003e\n\u003cli\u003eH3 thread limit for controlled thread tolerance in standard fitment applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or field-use tap for any application requiring a 3\/8-16 UNC right-hand thread in general mechanical, industrial, or trade service work.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap should be installed in a proper tap wrench or tapping head rated for the thread size. Always apply cutting fluid appropriate to the workpiece material before and during tapping to prevent galling and extend tool life. Back the tap out periodically to break and clear chips, especially in deeper holes. Follow applicable workplace safety standards and ensure the workpiece is securely fixtured before beginning any threading operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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: H3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Style\u003c\/strong\u003e: Plug\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\u003eOverall Length\u003c\/strong\u003e: 2-15\/16 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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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-20708\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IMPORT-GENERIC","offers":[{"title":"Default Title","offer_id":51715868557618,"sku":"BDNA-20708","price":18.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a4b052f9008b085615aaecec1f867747.jpg?v=1788519242","url":"https:\/\/voomisupply.com\/products\/import-bdna-20708-straight-flute-tap-3-8-16-unc-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
