Machined from high speed steel with a bright uncoated finish, this tap delivers reliable performance in hand-tapping and low-speed machine applications. The plug chamfer — typically 3 to 5 threads of lead — is the standard choice for through-holes and blind holes with adequate depth. At 3-13\/16 inches overall length, the tap provides sufficient clearance for standard tap wrench work. Class of fit 3B and thread limit H3 confirm this tap cuts to a tolerance appropriate for close-fit threaded assemblies.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for production shops, maintenance facilities, and toolrooms requiring 5\/8-27 UNS internal threads. The UNS (Unified National Special) thread form is used where a non-standard pitch is specified by design — in this case, 27 threads per inch on a 5\/8-inch major diameter. Machinists, toolmakers, and maintenance technicians working on specialty assemblies, fluid fittings, or custom hardware encounter this thread series regularly. The 4-flute straight-flute geometry provides stable cutting action and suits a range of material hardnesses typical in trade and industrial settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-27 UNS thread form — non-standard 27 TPI pitch on a 5\/8-inch major diameter\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer with 3 to 5 thread lead for versatile use in through-holes and deep blind holes\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — compatible with most cutting fluids and tapping compounds\u003c\/li\u003e\n  \u003cli\u003e4-flute straight-flute design for stable chip control and consistent thread quality\u003c\/li\u003e\n  \u003cli\u003eClass 3B fit with H3 thread limit for close-tolerance threaded assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard tap wrenches and low-speed tapping machines capable of accepting a 5\/8-27 UNS plug tap.

Always apply an appropriate cutting fluid or tapping compound for the workpiece material to reduce heat and extend tool life. Ensure the tap is started perpendicular to the workpiece surface to prevent thread misalignment. Do not force a tap through material resistance — back off periodically to break chips and clear the flutes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-27\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\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\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Style\u003c\/strong\u003e: Straight Flute\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: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-13\/16 inches\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\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: JY4846218\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689372778802,"sku":"JY4846218","price":82.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7b57caa86c222e40d1ce295756b8dddb.jpg?v=1788258478","url":"https:\/\/voomisupply.com\/products\/value-collection-jy4846218-hand-tap-5-8-27-uns-plug-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
