Built from high speed steel with a bright uncoated finish, this tap features a taper chamfer that guides the tool gradually into the workpiece for controlled thread engagement. It carries a Class 2B fit with an H3 thread limit, delivering threads within standard tolerance for most general-purpose fastener assemblies. Overall length is 2.125 inches with a thread length of 0.38 inches (19.05 mm). Licensed machinists, tool-and-die technicians, and maintenance mechanics use this tap for hand-tapping operations in production and repair environments.\u003c\/p\u003e\u003cp\u003eThe C54277 is suited for both blind hole and through-hole threading operations. The taper chamfer distributes cutting load across several leading threads, making it the preferred starting tap when no thread exists in the hole. It is compatible with a range of workpiece materials including alloy steel, carbon steel, aluminum, and free-machining stainless steel. The 4-flute straight-flute geometry provides good chip clearance in shorter threading passes typical of 8-32 fastener work on light structural and mechanical assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e8-32 UNC thread form, Class 2B fit, H3 thread limit for standard tolerance assemblies\u003c\/li\u003e\n\u003cli\u003eTaper chamfer distributes cutting load for smooth thread entry in blind and through holes\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction provides wear resistance across common ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for use with cutting fluids or dry in aluminum and free-machining steels\u003c\/li\u003e\n\u003cli\u003e4-flute straight-flute design offers stable cutting action on short-length threading passes\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, standard for the vast majority of fastener applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for blind hole and through-hole threading in alloy steel, carbon steel, aluminum, and free-machining stainless steel workpieces requiring 8-32 UNC internal threads at Class 2B fit.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is intended for use by machinists and maintenance technicians operating manual tap wrenches or low-speed tapping fixtures. Always secure the workpiece firmly and ensure the pilot hole diameter is correct for 8-32 UNC threading before starting. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve thread finish. Do not force the tap if resistance increases unexpectedly — back off to break chips and clear the flutes before continuing.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 8-32\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: H3\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\u003eOverall Length\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.38 inches (19.05 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.168 inches (4.27 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.25 inches (6.35 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.131 inches (3.33 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\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\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: C54277\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51712513245490,"sku":"C54277","price":20.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c9ac235bfbaad313885aaacb27bdf399.jpg?v=1788486356","url":"https:\/\/voomisupply.com\/products\/cleveland-c54277-hand-tap-8-32-unc-taper-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
