Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers reliable performance across a range of ferrous and non-ferrous workpiece materials. The plug chamfer — typically 3 to 5 threads of lead — makes this tap well-suited for through-hole applications where partial thread engagement at entry is acceptable. With an H3 thread limit, it produces threads in the middle tolerance range of the 3B fit class, giving machinists consistent clearance for standard fastener assembly.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in general machining and maintenance environments wherever 3\/8-20 UNS threads are required — including custom thread applications that fall outside the standard UNC and UNF series. Typical install scenarios include repair work, prototype fabrication, and production runs in machine shops, maintenance facilities, and tool rooms. It is installed by machinists and maintenance professionals using a standard tap wrench, tapping head, or CNC rigid-tapping setup. Right-hand thread direction matches conventional fastener rotation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-20 UNS thread form for non-standard pitch applications outside UNC and UNF series\u003c\/li\u003e\n  \u003cli\u003e4 straight flutes provide strength and chip clearance in through-hole tapping operations\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer provides gradual thread engagement for through-hole and open-ended blind-hole work\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit ensures consistent 3B class of fit across production runs\u003c\/li\u003e\n  \u003cli\u003eHSS construction supports use at moderate cutting speeds in a variety of materials\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for use with standard cutting fluids\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or production tap for any application requiring a right-hand 3\/8-20 UNS internal thread with a 3B class of fit.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eAlways secure the workpiece firmly and use appropriate cutting fluid or tapping compound for the material being threaded. Power down or disengage the tapping head before changing taps or clearing chips. Do not force the tap if resistance increases suddenly — back off to break chips before continuing. Straight flute taps are best suited for through-holes or shallow blind holes where chips can exit freely.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 3B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\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 (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOversize\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\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: JY4842209\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691602575666,"sku":"JY4842209","price":63.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a046ef16113208cf0cd275f3499c7178.jpg?v=1788287655","url":"https:\/\/voomisupply.com\/products\/value-collection-jy4842209-straight-flute-tap-3-8-20-uns","provider":"Voomi Supply","version":"1.0","type":"link"}
