This range extends Metro's Hand Tap catalog to cover pipe-specific thread standards — BSP (British Standard Pipe), and combined NPT/BSPT (National Pipe Thread / British Standard Pipe Tapered) — essential for plumbing, gas fitting and pipefitting work where fluid-tight threaded connections are required, as distinct from general mechanical fastening threads.

Unlike the general-purpose BSW/BSF/UNF/UNC taps, pipe thread taps like these are specifically designed to cut the tapered or parallel threads needed for pipe joints to seal properly under pressure. Getting the correct standard matters significantly here — BSP, NPT and BSPT are not interchangeable, and using the wrong tap will produce a thread that doesn't seal correctly with fittings designed to another standard.

Covering sizes from 1/8" up to 2" across both standards, and sold in sets of 2, this range serves plumbers, gas fitters, and industrial pipework fabricators needing to cut accurate, standard-compliant pipe threads.
