Spiral point geometry pushes chips forward through the hole during cutting, making it the right tool for through-hole threading operations in production and repair environments. The plug chamfer — typically 3 to 5 threads — provides an easy start and handles the majority of general-purpose tapping work. At 2.9375 inches overall length with a 0.75 inch thread length, this tap fits standard tap holders and drill press setups. The H2 thread limit and Class 2B fit designation ensure threads meet standard tolerance requirements for most fastener assemblies. Licensed machinists, maintenance technicians, and trade professionals working in fabrication or field repair will find this a reliable general-purpose tap.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for through-hole threading in alloy steel, carbon steel, and aluminum workpieces. It is commonly used in HVAC, plumbing, and electrical panel fabrication shops where 3\/8-16 fasteners are standard. The right-hand thread direction and 3-flute configuration handle most machine tapping and hand tapping scenarios in these materials without coolant-through features, making it appropriate for bench work and light CNC or drill press operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSpiral point geometry pushes chips forward, optimized for through-hole threading\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 UNC thread form, Class 2B fit, H2 thread limit for standard tolerance assemblies\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across steel and aluminum workpieces\u003c\/li\u003e\n  \u003cli\u003eBright finish with no coating — suitable for use with cutting oil or tapping fluid\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer provides easy thread start for general-purpose tapping\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, 3 flutes, no coolant-through requirement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for through-hole threading in alloy steel, aluminum, and carbon steel.

Secure the workpiece firmly before tapping and ensure the tap is aligned perpendicular to the hole to prevent tap breakage. Apply appropriate cutting oil or tapping fluid to extend tool life and improve thread quality. When reversing to break chips during hand tapping, use deliberate, controlled strokes to avoid overloading the flutes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\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: H2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Through-Hole Threading\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: Bright\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Aluminum, Carbon Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.9375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.381 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.51 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 7.26 mm\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: 1011\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0753 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: CLEVELAND\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C57175\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51697970610482,"sku":"C57175","price":30.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dae972037d02f7c2fec26c7e5e7b3b50.jpg?v=1788356371","url":"https:\/\/voomisupply.com\/products\/cleveland-c57175-spiral-point-tap-3-8-16-unc-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
