Tap Set Carbon Steel NPT Thread
A tap and die set is a two-in-one instrument for cutting threads around holes and into threads. The tap is used to cut threads in holes where thread fasteners are positioned, while the die is used to cut threads on steel rods. NPT is an American standard thread that stands for National Pipe Thread. Male external threads are referred to as MPT, MNPT, or NPT (M), while female internal threads are referred to as FPT, FNPT, or NPT(F). Except with NPTF, a thread sealer must always be applied to establish a leak-free seal.
