Metro's Complete Sets of Taps & Round Dies bring together everything needed for internal and external threading in a single, organized kit — taps, dies and accessories packed into an attractive, rust-protective metal box. Rather than sourcing individual taps and dies separately, these sets give workshops, mechanics and fabricators a ready-to-use threading toolkit covering a defined range of sizes in one purchase.

The metal box construction protects the tools from rust and damage during storage, keeping the set organized and each tool easy to locate when needed — a meaningful practical advantage over loose tools rattling around in a drawer or toolbox. Sets are available across multiple thread standards, including BSW, BSF, UNF, metric (DIN and S.I.), BA (British Association) and pipe threads in BSP and NPT, letting buyers choose a set matched to the specific standard their work requires.

Set sizes range from compact kits covering a handful of common sizes up to comprehensive sets spanning a wide range from 1/8" up to 1-1/2", suited to everything from routine maintenance work to fully equipped workshop threading stations. Customised box sizes are also available for buyers with specific requirements beyond the standard set offerings.
