Built from Vanadium High Speed Steel (HSS-E) with a steam oxide coating, this tap offers improved lubricity and corrosion resistance during cutting operations. The spiral point geometry pushes chips forward ahead of the cutting zone, making it well-suited for through-hole threading where chip evacuation is critical. With a 3-flute design, H5 thread limit, and right-hand thread direction, it produces consistent, accurate threads without oversizing. Licensed machinists, tool-and-die technicians, and maintenance mechanics are the primary users of this tap.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for use in through-hole threading operations across a wide range of workpiece materials. The HSS-E construction and steam oxide finish support use in aluminum, low-carbon steel, medium-carbon steel, high-carbon steel, alloy steel, die steel, stainless steel, and cast iron. It is commonly used in production machining, maintenance and repair, and tool-and-die work where a 3\/8-24 UNF fine thread is required. The plug chamfer style makes it appropriate for starting threads from a flat or pre-drilled surface where a full-depth thread is needed from the entry side.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSpiral point geometry pushes chips forward for clean through-hole threading\u003c\/li\u003e\n  \u003cli\u003eVanadium High Speed Steel (HSS-E) construction for extended tool life across hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eSteam oxide coating improves lubricity and reduces galling during tapping\u003c\/li\u003e\n  \u003cli\u003eH5 thread limit ensures accurate fit within standard UNF tolerance class\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer style for starting threads in through-hole applications\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, no coolant-through, non-interrupted thread form\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for threading 3\/8-24 UNF through-holes in workpiece materials including aluminum, hardened steel, stainless steel, high-carbon steel, low-carbon steel, medium-carbon steel, alloy steel, die steel, and cast iron.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap is installed by machinists or tool-and-die technicians using a tap wrench, tapping head, or CNC spindle. Ensure the workpiece is securely fixtured and the pilot hole is drilled to the correct tap drill diameter for 3\/8-24 UNF before tapping. Apply appropriate cutting fluid for the workpiece material to reduce heat and extend tap life. Follow all machine guarding and lockout procedures when tapping on power equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-24 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: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Style\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: H5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Vanadium High Speed Steel (HSS-E)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Steam Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.937 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.74 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.381 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: 280\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.081 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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2841801\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728491184434,"sku":"2841801","price":41.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/90ba695c8002572e681037bae3b7ed62.jpg?v=1788692058","url":"https:\/\/voomisupply.com\/products\/osg-2841801-spiral-point-tap-3-8-24-unf-plug-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
