It features a plug chamfer and two flutes, with a right-hand thread direction and an H3 thread limit for consistent 2B class-of-fit tolerances. The tap is manufactured from high-speed steel and finished with a steam oxide coating that reduces friction and helps resist corrosion during use. Overall length is 2.375 inches with a thread length of 0.54 inches and a shank diameter of 0.194 inches. Machinists, tool-and-die professionals, and maintenance technicians use this tap for production and repair threading applications.\u003c\/p\u003e\n\u003cp\u003eThe 1612401 is suited for tapping 10-32 UNF threads in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, and hardened steel. Its spiral point geometry pushes chips forward ahead of the cutting zone, making it well-matched for through-hole applications where chip clearance is a priority. The plug chamfer provides a gradual lead-in that distributes cutting load across several threads, reducing tool stress in both manual and machine tapping setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e10-32 UNF thread form with H3 thread limit for reliable 2B class-of-fit tolerance control\u003c\/li\u003e\n  \u003cli\u003eSpiral point design pushes chips forward, optimized for through-hole tapping\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer for gradual thread engagement and reduced cutting force\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides toughness across a broad material range\u003c\/li\u003e\n  \u003cli\u003eSteam oxide coating reduces friction and provides light corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction; no coolant-through feature required for standard applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, and hardened steel.

Ensure the workpiece is securely fixtured and the pilot hole diameter is correct for 10-32 UNF before starting. Apply cutting fluid appropriate to the workpiece material to extend tool life and improve thread quality. Reverse the tap periodically when hand-tapping harder materials to break chips and prevent binding.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 10-32\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\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: H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eOverall Length\u003c\/strong\u003e: 2.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.54 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.194 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\u003c\/strong\u003e: Steam Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 105A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.015 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: 1612401\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51743185371442,"sku":"1612401","price":34.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2204f8fde5a8e57ff6a347568264d182.jpg?v=1788843679","url":"https:\/\/voomisupply.com\/products\/osg-1612401-spiral-point-tap-10-32-unf-2-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
