Built from vanadium high-speed steel (HSS-E) and finished with a steam oxide coating, this tap handles through-hole applications where chip flow forward ahead of the cutting edges is practical and efficient. The plug chamfer distributes the cutting load across several leading threads, making it suitable for production threading and general-purpose machine tapping. It carries a 2B class of fit and H5 thread limit, giving machinists the tolerance control needed for standard fastener fitment. Overall length is 4.252 inches with a thread length of 1.21 inches and a shank diameter of 0.59 inches.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in CNC machining centers, manual mills, drill presses, and tapping machines where through-hole 3\/4-16 UNF threads are required. The spiral point geometry pushes chips forward through the hole rather than packing them into flutes, which makes it well suited for medium- to high-volume production runs in ferrous and non-ferrous materials. Typical installers include machinists, tool and die makers, and maintenance technicians working in job shops, manufacturing facilities, and industrial maintenance environments. It is sold individually and fits Series 280 tooling context.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4-16 UNF thread form with right-hand cutting direction and 2B class of fit\u003c\/li\u003e\n  \u003cli\u003eVanadium high-speed steel (HSS-E) construction for improved wear resistance and toughness\u003c\/li\u003e\n  \u003cli\u003eSteam oxide coating reduces friction and provides corrosion resistance during storage and use\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer with 3 flutes distributes cutting load and suits through-hole tapping\u003c\/li\u003e\n  \u003cli\u003eH5 thread limit for consistent tolerance control in standard fastener applications\u003c\/li\u003e\n  \u003cli\u003eSpiral point geometry pushes chips forward, reducing chip packing in production environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for threading 3\/4-16 UNF through-holes in aluminum, cast iron, alloy steel, die steel, low-carbon steel, medium-carbon steel, high-carbon steel, stainless steel, and hardened steel workpieces.

Ensure the workpiece is securely fixtured and the spindle is aligned axially with the pre-drilled hole before engaging the tap. Use an appropriate cutting fluid for the workpiece material — sulfurized oil for ferrous metals and a water-soluble coolant for aluminum. Inspect the tap for chipping or wear before each production run and replace at the first sign of edge deterioration to avoid thread damage or tap breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-16 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\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\u003eClass of Fit\u003c\/strong\u003e: 2B\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: 4.252 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.21 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.59 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOversize\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: 0.335 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: 2843801\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51750575243570,"sku":"2843801","price":142.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bb5bba56e902b0c53c13e00bc954c740.jpg?v=1788916892","url":"https:\/\/voomisupply.com\/products\/osg-2843801-spiral-point-tap-3-4-16-unf-plug-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
