Built from high speed steel (HSS) with a bright, uncoated finish, it features a taper chamfer that eases thread entry and distributes cutting forces across the lead threads. The tap has four flutes, a thread limit of H2, and a class of fit rating of 2B, making it suitable for standard-tolerance threaded fastener applications. Overall length is 2.375 inches with a thread length of 0.5 inches. Machinists and maintenance technicians use this tap with a tap wrench or tapping head in manual or low-speed machine setups.\u003c\/p\u003e\u003cp\u003eThis tap is rated for use in alloy steel, aluminum, carbon steel, and free-machining stainless steel. The taper chamfer style — typically 8 to 10 threads of lead — makes it well suited for starting threads cleanly in open setups or when threading from scratch rather than chasing existing threads. It is commonly used in general metalworking shops, MRO facilities, and field maintenance applications where standard 10-24 UNC threaded holes are required. Right-hand thread direction aligns with standard right-hand fasteners throughout the UNC thread system.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e10-24 UNC right-hand thread, H2 thread limit, 2B class of fit for standard-tolerance applications\u003c\/li\u003e\n\u003cli\u003eTaper chamfer provides gradual thread engagement, ideal for starting new holes\u003c\/li\u003e\n\u003cli\u003eFour straight flutes in bright HSS for general-purpose cutting across a range of metals\u003c\/li\u003e\n\u003cli\u003eCompatible with both blind hole and through-hole threading operations\u003c\/li\u003e\n\u003cli\u003eShank diameter of 0.194 inches and 0.25-inch square drive for standard tap wrenches and holders\u003c\/li\u003e\n\u003cli\u003eNo coolant-through requirement — suitable for hand tapping and bench work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in alloy steel, aluminum, carbon steel, and free-machining stainless steel workpieces requiring 10-24 UNC internal threads.

Apply cutting fluid appropriate to the workpiece material to reduce friction and extend tap life. Use a tap wrench with steady, aligned pressure — back off a quarter turn periodically to break chips, especially in blind holes. Never force a tap against resistance; a jammed tap in a blind hole is difficult to remove without damaging the part.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 10-24\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\u003eChamfer Type\u003c\/strong\u003e: Taper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H2\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: 2.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.5 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 Length\u003c\/strong\u003e: 0.25 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\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\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eSeries\u003c\/strong\u003e: 1001\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: CLEVELAND\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C54321\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51694752563506,"sku":"C54321","price":21.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d88c0a1ce21bc7110e0e09a1455112a3.jpg?v=1788328044","url":"https:\/\/voomisupply.com\/products\/cleveland-c54321-hand-tap-10-24-unc-taper-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
