The set includes all three chamfer styles — bottoming, plug, and taper — giving machinists and maintenance technicians the flexibility to start, advance, and finish a thread in one kit. Each tap is machined from high-speed steel (HSS) for durability across ferrous and non-ferrous materials. A gold oxide finish provides light corrosion resistance and reduces friction during cutting. Overall length is 2 inches, and each tap features 3 flutes for chip evacuation during threading operations. Thread limit is H2, indicating a standard tolerance class for general-purpose UNF applications.\u003c\/p\u003e\u003cp\u003eThis tap set is suited for light-duty threading tasks in manufacturing, maintenance, and repair environments. The 6-40 UNF thread specification is common in precision assemblies, instrument panels, electronics enclosures, and small mechanical components where a fine thread pitch is required for greater holding strength in thin or small fastening applications. Electricians, instrumentation technicians, and general maintenance mechanics will encounter this thread size in control panel work and small equipment repair.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThree-piece set includes bottoming, plug, and taper chamfer taps for complete threading in one kit\u003c\/li\u003e\n\u003cli\u003e6-40 UNF thread specification for fine-pitch, small-diameter applications\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for use across a range of metals\u003c\/li\u003e\n\u003cli\u003eGold oxide finish reduces friction and provides light surface protection\u003c\/li\u003e\n\u003cli\u003eH2 thread limit for standard general-purpose tolerance\u003c\/li\u003e\n\u003cli\u003e2-inch overall length with 3-flute geometry for efficient chip clearance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or workshop tap set for 6-40 UNF threading applications in general machining, maintenance, and repair operations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThreading operations should be performed with a calibrated tap handle or tap wrench sized for the tap shank. Secure the workpiece firmly before beginning. Use appropriate cutting fluid to extend tap life and improve thread finish.
