Built from high-speed steel with a bright, uncoated finish, this tap delivers reliable thread-forming performance in ferrous and non-ferrous materials. The taper chamfer eases entry into the workpiece and distributes cutting load across the leading flutes, reducing the risk of tap breakage during starting. At 2-23\/32 inches overall length and featuring 4 flutes, it is suited for use in drill presses, CNC machining centers, and manual tapping operations. A 3B class of fit and H3 thread limit ensure threads meet standard tolerance requirements for typical mechanical assemblies.\u003c\/p\u003e\n\u003cp\u003eThis tap is appropriate for threading through-holes in production and maintenance machining environments. Machinists, tool-and-die tradespeople, and maintenance technicians use this style of tap when threading mild steel, aluminum, brass, and similar materials to a 5\/16-24 UNF specification. The taper chamfer makes it particularly effective as a starting tap in hand or machine tapping sequences, especially where hole alignment and entry control are priorities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-24 UNF thread standard with right-hand thread direction\u003c\/li\u003e\n  \u003cli\u003eTaper chamfer for controlled entry and reduced starting torque\u003c\/li\u003e\n  \u003cli\u003e4 straight flutes for chip clearance in through-hole applications\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit meets 3B class of fit tolerances\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for durability across common workpiece 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 an OEM-style replacement or direct-use tap for applications requiring a 5\/16-24 UNF straight flute taper tap with a 3B class of fit in standard machining and maintenance threading operations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap is installed by machinists and maintenance tradespeople using standard tapping equipment; ensure the workpiece is securely fixtured and the pilot hole is drilled to the correct tap drill size for 5\/16-24 UNF before beginning. Apply appropriate cutting fluid for the workpiece material to extend tap life and improve thread finish. Never force a tap against resistance; back off periodically to break chips and prevent binding. Follow applicable shop safety procedures and machine guarding requirements when power tapping.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\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\u003eChamfer Type\u003c\/strong\u003e: Taper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-23\/32 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: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.49 pounds\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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: K008408AS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51755846664498,"sku":"K008408AS","price":19.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/93817beffd0855559a734375b5f53a96.jpg?v=1788960425","url":"https:\/\/voomisupply.com\/products\/hertel-k008408as-straight-flute-tap-5-16-24-unf-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
