Choosing the right tool

A die makes threads on the outside of a rod. Use a tap when you need threads inside a drilled hole. This 2.5mm die is distinct from the 4mm version and should be selected to match the fastener and mating part in your project.

Before you start

Check the required thread pitch and holder fit before purchase; nominal diameter alone does not establish compatibility. Use a suitable die holder, keep the tool aligned with the workpiece and follow the tool maker's threading guidance.
