Regal 014052AS is a 2-1/2-4 NC hand plug tap with a 6-flute straight-flute design for cutting internal threads in holes to accept 2-1/2 in diameter, 4 TPI UNC threads. It features a right-hand cut and an H7 thread limit, and is manufactured from bright high-speed steel (HSS) with a bright finish. This hand tap is intended for manual tapping with a tap wrench, providing the chamfered entry typical of plug taps to finish threads near the bottom of the hole. Ideal for fabricating large-diameter internal threads in metal parts, fixtures, or housings where a 2-1/2 in diameter and 4 TPI are required.
