Built from vanadium high-speed steel (HSS-E) with a steam oxide coating, this tap is suited for production tapping in both hand and machine applications. The spiral point geometry pushes chips forward ahead of the cutting zone, making it effective in through-hole applications where chip evacuation is critical. With a thread limit of H4 and a Class 2B fit, it produces threads within tight tolerance for reliable fastener engagement in precision assemblies.\u003c\/p\u003e\n\u003cp\u003eThe OSG 2813901 is used across a broad range of materials including aluminum, low-carbon steel, medium-carbon steel, high-carbon steel, alloy steel, die steel, stainless steel, and cast iron. It is a practical choice for HVAC equipment assembly, electrical enclosure fabrication, and general mechanical work where 10-32 UNF threaded holes are required in through-hole configurations. The plug chamfer makes it appropriate for starting threads from the top of a through-hole without a starter tap.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSpiral point design pushes chips forward for clean through-hole tapping\u003c\/li\u003e\n  \u003cli\u003eVanadium high-speed steel (HSS-E) construction for extended tool life in a wide range of materials\u003c\/li\u003e\n  \u003cli\u003eSteam oxide coating reduces friction and improves lubrication retention during cutting\u003c\/li\u003e\n  \u003cli\u003eH4 thread limit with Class 2B fit for precise tolerance control\u003c\/li\u003e\n  \u003cli\u003e3-flute configuration balances chip clearance and cutting edge strength\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction compatible with standard tapping setups and tap handles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for tapping 10-32 UNF through-holes in aluminum, hardened steel, stainless steel, high-carbon steel, low-carbon steel, medium-carbon steel, alloy steel, die steel, and cast iron.

Apply cutting fluid appropriate to the workpiece material before and during tapping. Ensure the pilot hole is drilled to the correct diameter for 10-32 UNF before tapping. Follow standard shop safety practices and secure the workpiece firmly before beginning the operation.\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\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\u003eMaterial\u003c\/strong\u003e: Vanadium High-Speed Steel (HSS-E)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Steam Oxide\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: H4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.374 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.492 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\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: 0.02 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: 2813901\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51732031340850,"sku":"2813901","price":31.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ebfa43e58614faccdbcd800a1ae86f41.jpg?v=1788738394","url":"https:\/\/voomisupply.com\/products\/osg-2813901-spiral-point-tap-10-32-unf-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
