Built from high-speed steel with a bright uncoated finish, this tap features a plug chamfer and two flutes arranged in a spiral point geometry. The spiral point design pushes chips ahead of the cutting edge rather than back through the flutes, making it well suited for through-hole threading operations. Right-hand thread direction and an H2 thread limit provide controlled tolerances appropriate for standard UNF fastener fits. Machinists, tool-and-die workers, and maintenance technicians across manufacturing and repair environments regularly rely on this tap type.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in through-hole threading of steel, aluminum, cast iron, and similar materials where a 5\/16-24 UNF thread form is required. The plug chamfer — typically 3 to 5 threads of taper — allows the tap to start in a pre-drilled hole without requiring a starter tap. Its compact size and standard shank geometry make it compatible with tap handles, tapping heads, and CNC or manual drill press setups. It is well suited for production threading, maintenance and repair operations, and general machine shop work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-24 UNF thread form for fine-pitch threading in through holes\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides durability across a wide range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eSpiral point geometry drives chips forward, reducing clogging in through-hole applications\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer for easy hole entry without a separate starter tap\u003c\/li\u003e\n  \u003cli\u003eH2 thread limit for consistent, close-tolerance UNF thread fits\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 spiral point tap for through-hole threading applications requiring a 5\/16-24 UNF thread form.

Ensure the workpiece hole is drilled to the correct tap drill size for a 5\/16-24 UNF thread before tapping. Secure the workpiece firmly before operation to prevent movement that can break the tap. Reverse the tap periodically during hand tapping to break chips and reduce torque buildup.\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H2\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: 0.6 pounds\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: K008417AS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51738350420274,"sku":"K008417AS","price":24.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/db7591f20c19edf2133596def9e009fa.jpg?v=1788798531","url":"https:\/\/voomisupply.com\/products\/hertel-k008417as-spiral-point-tap-5-16-24-unf-2-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
