The DIN 382 HSS-G hexagon dies for metric threads are designed for cleaning, correcting and restoring external ISO metric threads according to DIN 13 on screws, pins, studs, threaded rods and already machined mechanical components. Their hexagonal shape allows them to be driven with standard spanners, sockets or common manual tools, making them especially practical for maintenance, assembly and repair operations, particularly in difficult-to-access areas where a conventional round die stock may be inconvenient or impossible to use.

The HSS-G construction provides good wear resistance, stable thread profile and accurate thread restoration. The 60° thread profile and 6g tolerance are suitable for standard external metric threads and help correct burrs, minor deformation, machining residues, light oxidation or superficial thread damage. Compared with traditional circular dies, hexagon dies are more focused on restoring and cleaning existing threads than on cutting new threads from solid material, because their wrench-drive design makes them ideal for quick interventions directly on assembled components.

The correct version must be selected according to nominal thread size, pitch, available space around the component and the wrench or socket used for operation. They are particularly useful on installed studs, protruding screws, threaded shafts, tie rods and components mounted on machines, equipment or industrial systems.

To obtain accurate thread restoration, the die must be started coaxially with the existing thread, suitable cutting lubricant must be used and progressive feed should be applied while periodically clearing chips, burrs or residues removed from the thread profile. Misaligned starting, excessive thread damage or forced use of the tool may worsen the thread geometry, increase cutting effort or compromise the fit with the nut or female component. These hexagon dies are suitable for mechanical workshops, maintenance technicians, production departments, automotive work, toolrooms, industrial assembly and repair operations where external metric threads must be quickly restored without complex disassembly.
