Built from high-speed steel (HSS) with a bright, uncoated finish, this tap cuts 5\/16-18 UNC right-hand threads with a plug chamfer that provides a smooth lead-in for general-purpose tapping. It carries an H11 thread limit and is manufactured oversize by 0.005 inches to account for material spring-back in ductile metals. The overall length is 2-23\/32 inches. Machinists, toolroom technicians, and maintenance mechanics will find this tap suited to everyday production and repair tapping tasks.\u003c\/p\u003e\n\u003cp\u003eThis tap is used wherever a standard 5\/16-18 UNC internal thread is required. The straight flute geometry is best suited for through-hole applications and short blind holes where chips can exit freely. The plug chamfer, with its moderate lead-in, makes this tap appropriate for use in hand tapping, drill press setups, and CNC tapping cycles where the workpiece material is steel, aluminum, cast iron, or similarly machinable metals. It is a single-piece unit sold individually.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC thread form for standard unified coarse-pitch internal threading\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides good hardness and wear resistance across a broad range of work materials\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer (typically 3-5 thread lead) for reliable starting in through-holes and shallow blind holes\u003c\/li\u003e\n  \u003cli\u003eH11 thread limit with 0.005-inch oversize allowance to compensate for material spring-back\u003c\/li\u003e\n  \u003cli\u003eStraight flute design promotes chip clearance in through-hole tapping operations\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for use with cutting fluid or tapping compound\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or toolroom tap for any application requiring a 5\/16-18 UNC right-hand internal thread in machinable metals and plastics.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap is installed by machinists and maintenance technicians using a tap wrench, tapping head, or CNC rigid-tapping setup. Before tapping, ensure the pilot hole is drilled to the correct tap drill diameter for 5\/16-18 UNC and that the workpiece is securely fixtured. Apply an appropriate cutting fluid or tapping compound to extend tool life and improve thread quality. Do not force the tap if resistance increases sharply, as this indicates chip buildup or misalignment that can cause breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18\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\u003eNumber of Flutes\u003c\/strong\u003e: 4\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 (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmount Oversize\u003c\/strong\u003e: 0.005 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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0093 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: JY8962532\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51695407595826,"sku":"JY8962532","price":17.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bcad78c2c0a65340edeac717809085b6.jpg?v=1788334683","url":"https:\/\/voomisupply.com\/products\/value-collection-jy8962532-5-16-18-unc-straight-flute-tap-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
