Operating on a cold-forming principle, this tap displaces material to generate strong, work-hardened threads. It carries a 3\/8-24 UNF thread specification with an H6 thread limit and a semi-bottoming chamfer, making it suitable for threading holes that require thread engagement close to the bottom. Made from high-speed steel and finished with a V coating, it is used by machinists and maintenance professionals in production and repair applications.\u003c\/p\u003e\u003cp\u003eThis tap is intended for use on carbon steel, alloy steel, stainless steel, aluminum, nickel, hardened steel, and titanium alloy workpieces. The semi-bottoming chamfer provides a balance between starting ease and bottom-hole thread reach, making it a practical choice for general tapping operations where full bottoming is not required but near-bottom thread depth is needed. It fits standard tapping chucks and tap holders sized for a 0.323-inch shank diameter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThread forming design produces work-hardened threads with no chips generated\u003c\/li\u003e\n\u003cli\u003e3\/8-24 UNF thread size with H6 thread limit for controlled tolerance fit\u003c\/li\u003e\n\u003cli\u003eSemi-bottoming chamfer for threading near the bottom of blind holes\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for durability across a wide range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eV finish coating for improved surface performance\u003c\/li\u003e\n\u003cli\u003eClass of fit 2B for standard internal thread applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for tapping operations in carbon steel, alloy steel, stainless steel, aluminum, nickel, hardened steel, and titanium alloy.

Ensure the tap is aligned perpendicular to the workpiece before applying torque to avoid tap breakage or thread distortion. Use a torque-limiting tapping attachment when possible. Always follow applicable shop safety procedures and manufacturer guidelines for spindle speed based on material and hole diameter.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eThread Limit\u003c\/strong\u003e: H6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Semi-Bottoming\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5433 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.4375 inches (1-7\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.323 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.242 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: V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Carbon Steel, Alloy Steel, Stainless Steel, Aluminum, Nickel, Hardened Steel, Titanium Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 16260\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 1626003008\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51731852558642,"sku":"1626003008","price":173.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3299a5522130241ca27ef656891389e6_eff016bf-b789-4a41-a7aa-b41ce40f6b89.jpg?v=1788735627","url":"https:\/\/voomisupply.com\/products\/osg-1626003008-thread-forming-sti-tap-3-8-24-unf-h6","provider":"Voomi Supply","version":"1.0","type":"link"}
