Made from high-speed steel (HSS) with a bright, uncoated finish, this tap handles right-hand threading operations in a wide range of shop and field environments. The plug chamfer style provides a gradual lead-in, making it well suited for through-hole applications where the tap can pass fully through the material. With 4 flutes and an H3 thread limit, it produces accurate 3B class-of-fit threads suitable for standard mechanical assemblies and fastener applications. Overall length is 3.8125 inches.\u003c\/p\u003e\u003cp\u003eThis tap is intended for machinists, tool-and-die makers, maintenance technicians, and trade professionals who need to cut or restore UNS-standard threads in steel, aluminum, cast iron, and similar machinable materials. The 5\/8-28 UNS thread form is used in specialized mechanical and instrument applications. The straight flute design is best suited for through-holes in materials that produce short, chippy chips, as the flutes do not provide active chip evacuation the way spiral-point or spiral-flute designs do.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/8-28 UNS thread form for specialized unified national special thread applications\u003c\/li\u003e\n\u003cli\u003ePlug chamfer provides a gradual 3-5 thread lead-in, suited for through-hole tapping\u003c\/li\u003e\n\u003cli\u003e4 straight flutes deliver rigid, accurate thread form in short-chipping materials\u003c\/li\u003e\n\u003cli\u003eH3 thread limit ensures consistent 3B class-of-fit tolerance across production runs\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction resists heat and wear during manual or machine tapping\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish for straightforward use across common workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in any standard tap holder, tapping head, or drill press setup accepting the appropriate shank diameter for this tool size.

Always ensure the workpiece is securely fixtured before tapping. Apply a suitable cutting fluid for the workpiece material to extend tap life and improve thread finish. Back the tap off periodically to break chips and prevent binding, and never force a tap against resistance, as HSS taps are brittle and subject to breakage under torsional overload.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-28\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\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\u003eOverall Length\u003c\/strong\u003e: 3.8125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: JY4846283\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51713118535986,"sku":"JY4846283","price":84.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8cb71b1b16ff56d7a9f4c185890e837f.jpg?v=1788491264","url":"https:\/\/voomisupply.com\/products\/value-collection-jy4846283-straight-flute-tap-5-8-28-uns-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
