Built from high speed steel with a bright uncoated finish, it features a plug chamfer, 4-flute geometry, and a right-hand thread direction. The tap conforms to a Class 3B fit with an H3 thread limit, making it suitable for close-tolerance threading applications. Overall length is 2.5 inches with a thread length of 0.63 inches. Machinists and tool-and-die technicians use this tap for both blind-hole and through-hole threading operations where consistent thread quality is required.\u003c\/p\u003e\u003cp\u003eThis tap is suited for manual tapping operations in job shops, maintenance environments, and production setups where hand tapping is the preferred method. It is appropriate for use in alloy steel, carbon steel, aluminum, and free-machining stainless steel. The 1\/4-20 thread size is one of the most common fastener standards in North American manufacturing, making this tap a high-frequency shop tool. It belongs to the CLEVELAND Series 1002 and is sold individually.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-20 UNC thread form with right-hand cutting direction\u003c\/li\u003e\n\u003cli\u003ePlug chamfer for starting threads in blind holes or through holes\u003c\/li\u003e\n\u003cli\u003e4-flute straight-flute geometry for chip control in a wide range of materials\u003c\/li\u003e\n\u003cli\u003eClass 3B fit, H3 thread limit for close-tolerance thread production\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction, bright uncoated finish\u003c\/li\u003e\n\u003cli\u003eCompatible with alloy steel, carbon steel, aluminum, and free-machining stainless steel\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for blind-hole and through-hole threading applications in alloy steel, carbon steel, aluminum, and free-machining stainless steel where a 1\/4-20 UNC Class 3B thread form is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eUse in a properly aligned tap wrench or tapping fixture to prevent tap breakage and maintain thread axis alignment.
