Spiral Point Tap: #4-40 UNC, 2 Flutes, Plug, 2B/3B Class of Fit, High Speed Steel, Bright Finish MPN:K008090AS

The spiral point tap measuring at size 7/8-14 UNF offers an unifiedcoarse threadform for applications requiring high tensile strength and hardness resistance such as aircraft assembly joints, automotive fastening solutions or other metal-on-metal installations demanding precision cutting of threads to maintain alignment between pieces being fitted; hence it finds usage across the aviation sector due to its capability to stand harsh environmental conditions. Its four flutes feature design makes thread cutting operation smoother by clearing chips away allowing for more accuracy in measurements preventing misalignment when tapping pan-heads or machine screws into workpiece materials made of steel, aluminum, brass among others . Made from high-speed steel -E hence it retains sharp edge longer lasting cutting tool thus maintaining its overall quality making it suitable even under extreme pressure conditions .
