It carries three flutes and an H2 thread limit, making it well suited for threading through-holes in a wide range of ferrous and non-ferrous workpiece materials. Overall length is 1-7\/8 inches with a 9\/16-inch thread length, a 0.141-inch shank diameter, and a square length of 0.1875 inches. Right-hand thread direction is standard. Machinists, tool and die makers, and maintenance technicians reach for this tap when producing or restoring UNS threads in production or repair settings.\u003c\/p\u003e\u003cp\u003eThis tap is designed for use in tapping operations on aluminum, cast aluminum, cast iron, high-carbon steel, low-carbon steel, and medium-carbon steel. The plug chamfer makes it appropriate for through-hole applications where the tap can run past the bottom of the required thread. The straight flute geometry works reliably in shorter-chipping materials and in applications where coolant-through tooling is not required or available. It fits standard tap holders sized for the 0.141-inch shank.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-36 UNS thread form, right-hand direction, H2 thread limit for close tolerance fits\u003c\/li\u003e\n\u003cli\u003eThree straight flutes for reliable chip handling in short-chipping materials\u003c\/li\u003e\n\u003cli\u003ePlug chamfer geometry suited to through-hole tapping applications\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction with bright, uncoated finish\u003c\/li\u003e\n\u003cli\u003eCoolant-through not required, simplifying use in manual or low-coolant setups\u003c\/li\u003e\n\u003cli\u003eCompact overall length of 1-7\/8 inches fits standard tap holders and tight workpiece clearances\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style straight flute plug tap for use in standard tap holders accepting a 0.141-inch shank diameter; compatible with aluminum, cast aluminum, cast iron, high-carbon steel, low-carbon steel, and medium-carbon steel workpiece materials per OSG Series 102 specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is installed and operated by a qualified machinist or maintenance technician using a standard tap wrench, tapping head, or CNC spindle set to right-hand rotation. Power down and de-energize any machine tool before changing or seating tooling. Verify correct pilot hole diameter for 4-36 UNS threads before tapping to avoid tap breakage. Do not reverse the tap under power without confirming the drive setup supports it.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-36 UNS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 36\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\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Style\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-7\/8 inches (1.874 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 9\/16 inches (0.370 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.141 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.11 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.6811 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, High-Carbon Steel, Low-Carbon Steel, Medium-Carbon Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 102\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.015 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: 1012800\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51740412313906,"sku":"1012800","price":22.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/326d7ab8b02d8071a42bd324ef4f1ff7_95d038c1-8237-48c9-adba-09472aea943e.jpg?v=1788824842","url":"https:\/\/voomisupply.com\/products\/osg-1012800-straight-flute-tap-4-36-uns-hss-plug","provider":"Voomi Supply","version":"1.0","type":"link"}
