This M24 x 3.0 HSS dienut is an external thread cutting die designed to cut or restore M24 × 3.0 metric threads (ISO metric coarse pitch) on rods, bolts and shafts. It is intended for use in a standard die stock (die holder) or compatible hand holder to reform or produce right‑hand external threads to metric tolerances used across engineering and maintenance work.

The die is manufactured from high speed steel (commonly M2 HSS), giving a hard cutting edge and good wear resistance. It is supplied with a precision ground thread profile and a chamfered lead to ease thread engagement. The product conforms to ISO metric thread form standards (ISO 68-1 / ISO 261 thread profile and ISO 965 tolerances where applicable) and aligns with common DIN/BS conventions for metric external threads (for example DIN 13 / BS 3643). The finish is a ground bright or black‑oxide surface to reduce rusting and improve chip flow; it is not stainless steel and should be stored oiled to avoid corrosion in humid environments.

Typical applications include on‑site maintenance and repair, fabrication of structural components, plant and machinery overhaul, automotive and heavy equipment thread restoration, and general engineering workshop use. The M24 × 3.0 size is widely used for larger fastenings in construction, agricultural machinery, mechanical assemblies and heavy plant equipment.

Key benefits of an HSS dienut are the material’s hardness and edge retention, which extend tool life when cutting ferrous and many non‑ferrous materials. When used with appropriate cutting fluid and correct feed, the die will cut clean threads in mild steel, alloy steels and softer stainless steels; compatibility with standard die stocks and metric tooling makes it straightforward to integrate into existing workshops. The ground profile delivers accurate thread form and good repeatability for repair and production tasks.

Duchy Fasteners stocks a broad range of die nuts and related threading tools in common metric sizes (commonly M3–M36), available individually or in multi‑packs, and can supply matching die holders and tapping accessories to complete your tooling set.
