Built from high-speed steel with a bright uncoated finish, this tap delivers reliable thread form in general-purpose machine tapping and hand tapping applications. It carries an H1 thread limit for close-tolerance work and features 4 flutes to provide adequate chip clearance in through-hole and shallow blind-hole applications. Overall length is 2-23\/32 inches with a thread length of 1-1\/8 inches, making it suited to standard tapping depths in production and maintenance environments.\u003c\/p\u003e\u003cp\u003eThis tap is intended for use in machine shops, maintenance facilities, and production lines where 5\/16-18 UNC threads are required. The plug chamfer  -  typically 3 to 5 threads of lead  -  positions it as the standard choice when starting a thread in a pre-drilled hole and running it through or to a moderate depth. Material applications include aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, and high-carbon steel, covering the most common workpiece materials encountered in general machining and fabrication.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/16-18 UNC thread form, right-hand direction\u003c\/li\u003e\n\u003cli\u003ePlug chamfer for standard through-hole and moderate blind-hole tapping\u003c\/li\u003e\n\u003cli\u003e4 straight flutes for chip clearance in a wide range of materials\u003c\/li\u003e\n\u003cli\u003eH1 thread limit for close-tolerance thread fit\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for durability across ferrous and non-ferrous workpieces\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish compatible with cutting oils and standard tapping fluids\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for tapping 5\/16-18 UNC threads in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, and high-carbon steel workpieces using standard tapping equipment.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is installed by machinists and maintenance technicians using a tap wrench, tapping head, or CNC tapping cycle. Always use an appropriately sized pilot hole per UNC tap drill charts before tapping. Apply a suitable cutting fluid or tapping compound for the workpiece material to extend tool life and improve thread quality. Secure the workpiece firmly and ensure the tap enters the hole square to avoid thread damage or breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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\u003eChamfer Type\u003c\/strong\u003e: Plug\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 (2.7205 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1-1\/8 inches (0.835 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 1.3228 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\u003eSquare Length\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.238 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\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Cast Aluminum, Cast Iron, Low-Carbon Steel, Medium-Carbon Steel, High-Carbon Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 101\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 1100700\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51739384971570,"sku":"1100700","price":24.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/326d7ab8b02d8071a42bd324ef4f1ff7_e182c392-a136-4d35-a955-abedfffce48b.jpg?v=1788813882","url":"https:\/\/voomisupply.com\/products\/osg-1100700-straight-flute-tap-5-16-18-unc-plug-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
