Built from vanadium high-speed steel and finished with a steam oxide coating, it resists wear and reduces friction during the threading operation. The spiral point geometry pushes chips ahead of the tap rather than backing them into the flute, making it well suited for through-hole applications. With an overall length of 4 inches and a reduced shank design, it reaches into recessed or deep-set bosses where a standard-length tap would not fit. Machinists, tool-and-die workers, and maintenance technicians install this tap using a standard tap wrench or CNC tapping head.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in production and maintenance threading of 10-32 UNF through holes in carbon steel, hardened steel, and stainless steel workpieces. The 4-inch overall length provides the reach needed for extended-depth fixtures, jigs, or assemblies where access is restricted. The H3 thread limit and Class 2B\/3B fit make it appropriate for standard tolerance fastener applications across both light manufacturing and heavy maintenance environments. It is sold individually and is part of OSG Series 397.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSpiral point plug geometry pushes chips forward through the hole, reducing chip clogging in through-hole threading\u003c\/li\u003e\n  \u003cli\u003eVanadium high-speed steel construction provides hardness and toughness for threading carbon steel, hardened steel, and stainless steel\u003c\/li\u003e\n  \u003cli\u003eSteam oxide finish reduces friction and provides corrosion resistance during storage and use\u003c\/li\u003e\n  \u003cli\u003e4-inch overall length with reduced shank extends reach into deep or obstructed workpiece locations\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit with Class 2B and 3B fit for standard UNF fastener tolerance requirements\u003c\/li\u003e\n  \u003cli\u003e3 right-hand flutes with right-hand thread direction; plug chamfer for starting in pre-drilled through holes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for threading 10-32 UNF through holes in carbon steel, hardened steel, and stainless steel.

Always secure the workpiece and ensure the tap is properly aligned with the pilot hole before applying torque to avoid tap breakage. Use a cutting fluid appropriate to the workpiece material, particularly when threading stainless steel. Inspect the tap for wear or chipping before each use and replace if the cutting edges show damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Type\u003c\/strong\u003e: Spiral Point\u003c\/li\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B, 3B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\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\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.4921 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 1.312 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\u003eSquare Size\u003c\/strong\u003e: 0.152 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReduced Shank\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Vanadium High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Steam Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Carbon Steel, Hardened Steel, Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 397\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.045 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: 1764701\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51730041241906,"sku":"1764701","price":82.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7ec4584289c96f0c9d29e49f2fa24ea4.jpg?v=1788710639","url":"https:\/\/voomisupply.com\/products\/osg-1764701-extension-tap-10-32-spiral-point-vanadium-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
