Built from high-speed steel with a bright finish, this tap is suited for production and maintenance threading operations where consistent thread quality and tool durability are required. The spiral point geometry pushes chips forward ahead of the tap, making it well-suited for through-hole applications. With 2 flutes and an H1 thread limit, it holds tight tolerances appropriate for standard UNF fastener fits. Overall length is 2.719 inches with a thread length of 0.724 inches and a shank diameter of 0.318 inches.\u003c\/p\u003e\u003cp\u003eThis tap is used in machine shop, maintenance, repair, and fabrication environments where 5\/16-24 UNF through-hole threading is required. Suitable for use in drill presses, CNC machining centers, and tapping machines. Material compatibility includes aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, and hardened steel, making it a versatile choice across general metalworking applications. It is a right-hand cut tap and does not require coolant-through tooling setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSpiral point design pushes chips forward, ideal for through-hole threading\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction provides durability across a broad range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eH1 thread limit for controlled tolerance fits on standard UNF fasteners\u003c\/li\u003e\n\u003cli\u003eBright finish with no coating for straightforward tool identification and general-purpose use\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, 2-flute configuration suited for machine tapping operations\u003c\/li\u003e\n\u003cli\u003eNo coolant-through requirement simplifies setup on standard equipment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for threading 5\/16-24 UNF through-holes in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, and hardened steel workpieces.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall in a rigid or floating tap holder appropriate for the machine being used; avoid hand-tapping in applications where thread accuracy is critical. Power down or de-energize the machine and secure the workpiece before loading the tap. Follow shop standard feeds and speeds for high-speed steel tooling based on workpiece material. Inspect the tap for wear or chipping before each use to prevent thread damage or tap breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-24 UNF\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.719 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.724 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.318 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupted Thread\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.055 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1221200\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51732191838514,"sku":"1221200","price":30.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/65398680501eed073eebed0f73ce970c_d1fa9c26-e8b5-46ae-b88e-a2051f420c8d.jpg?v=1788740238","url":"https:\/\/voomisupply.com\/products\/osg-1221200-spiral-point-tap-5-16-24-unf-plug-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
