Built from high speed steel with a bright uncoated finish, it runs a plug chamfer entry and four flutes to efficiently clear chips during manual or machine-assisted tapping operations. The tap measures 2.938 inches overall length with a 0.75-inch thread length, and carries a Class 2B fit with an H5 thread limit for standard commercial tolerance threading. This tool is installed by machinists, maintenance technicians, and toolroom professionals working in metalworking and fabrication environments.\u003c\/p\u003e\n\u003cp\u003eThe C54588 is suited for blind hole and through-hole threading applications across a broad range of workpiece materials. Its plug chamfer — typically 3 to 5 lead threads — makes it the standard choice for through-hole work and the most common starting tap in a tap set sequence. Series 1002 designation places it in Cleveland's standard hand tap line, appropriate for general-purpose threading tasks in job shop, production, and MRO settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-16 UNC thread form with right-hand direction for standard fastener thread cutting\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer entry for versatile use in through holes and moderately deep blind holes\u003c\/li\u003e\n  \u003cli\u003e4-flute straight-flute geometry promotes chip clearance in short-chipping materials\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides toughness and wear resistance across common metals\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no coating buildup to alter tap geometry or tolerance\u003c\/li\u003e\n  \u003cli\u003eH5 thread limit and Class 2B fit meet standard commercial threading specifications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in alloy steel, aluminum, carbon steel, and free-machining stainless steel workpieces.

Always secure the workpiece and ensure the hole is drilled to the correct tap drill diameter for a 3\/8-16 UNC thread before tapping. Apply appropriate cutting fluid for the workpiece material to reduce friction and extend tap life. Back the tap off periodically during operation to break and clear chips, particularly in blind hole applications.\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\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: H5\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: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Style\u003c\/strong\u003e: Straight Flute\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.938 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.75 inches (31.75 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.381 inches (9.68 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.286 inches (7.26 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.4375 inches (11.11 mm)\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\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Aluminum, Carbon Steel, Free-Machining Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading, Through-Hole Threading\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: 1002\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: C54588\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51723273896242,"sku":"C54588","price":32.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9e5f18f813a37e0c813cb9f62c07f4d0.jpg?v=1788602498","url":"https:\/\/voomisupply.com\/products\/cleveland-c54588-hand-tap-3-8-16-unc-plug-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
