Thread Dies

Thread dies are cutting tools used to create or restore external threads on shafts, bolts, rods, and studs. They are available in metric (M, MF) and inch systems (UNC, UNF, UNEF, BSP, NPT, BSW, BSF and more), including left-hand versions. They are essential for metalworking and maintenance tasks where accurate pitch, clean thread form, and reliable fit with nuts or mating components are required.

In this collection you'll find round (adjustable) dies and hex die nuts, suitable for use with die stocks and guides. Choose based on thread system, diameter and pitch (coarse/fine), cutting performance, and die material such as HSS for wear resistance and longer tool life. Baer options are available for consistent thread accuracy and repeatable results in demanding workshop conditions.

These tools are commonly used by machinists, maintenance technicians, and QC teams across manufacturing, construction, and industrial automation for thread repair, component fabrication, and on-site adjustments where dependable threading is critical.
