Built from high-speed steel with a bright uncoated finish, this tap produces 5\/16-18 UNC right-hand threads to a 3B class of fit with an H3 thread limit. It features four flutes and a plug chamfer, which provides a gradual lead-in that works well in through-hole applications. Overall length is 2-23\/32 inches with a thread length of 1-1\/8 inches. This is a Series 101 tap from OSG, a precision cutting tool manufacturer. Machinists, toolroom technicians, and maintenance mechanics use this tap in hand or machine tapping operations.\u003c\/p\u003e\u003cp\u003eThis tap is suited for through-hole tapping in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, and high-carbon steel. The plug chamfer style makes it a versatile choice for general-purpose production tapping and repair work across light manufacturing, maintenance, and fabrication environments. The 5\/16-18 UNC thread form is a standard unified coarse thread widely used in structural fastening and equipment assembly applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/16-18 UNC thread form with right-hand thread direction\u003c\/li\u003e\n\u003cli\u003ePlug chamfer for gradual thread engagement in through-hole applications\u003c\/li\u003e\n\u003cli\u003e4 flutes for efficient chip formation in a broad range of materials\u003c\/li\u003e\n\u003cli\u003eH3 thread limit and 3B class of fit for standard tolerance threading\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction provides durability across ferrous and non-ferrous workpieces\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for use with cutting fluids across many material types\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.

Secure the workpiece fully before beginning any tapping operation and use an appropriate cutting fluid for the material being tapped. When machine tapping, ensure the tap holder is aligned axially with the drilled hole to prevent tap breakage. Inspect the tap for wear or chipping before each use and replace when thread quality degrades.\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\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\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\u003eThread Length\u003c\/strong\u003e: 1-1\/8 inches\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\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\u003eNeck Length\u003c\/strong\u003e: 1.3228 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: 0.047 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: 1120700\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51743241142578,"sku":"1120700","price":22.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/930e76b95de6427c70f95788e32054a0.jpg?v=1788844396","url":"https:\/\/voomisupply.com\/products\/osg-1120700-straight-flute-tap-5-16-18-unc-hss-plug","provider":"Voomi Supply","version":"1.0","type":"link"}
