This is a 14 mm x 1.5 HSS dienut, right-hand, designed to cut or restore external ISO metric threads on rods, studs and shafts. It is intended for use in a standard die stock/holder to produce an M14 × 1.5 right‑hand thread where a controlled, repeatable external thread is required for assembly or repair.

The die is manufactured from M2 high‑speed steel (HSS) and supplied with a bright ground finish and a light preservative oil to reduce corrosion during storage. The thread form conforms to the ISO metric thread profile (referencing ISO 68‑1 for profile form and ISO 261/ISO 965 for nominal sizes and tolerances), and the die geometry is produced to customary DIN/BS die dimensional practice so it will sit correctly in standard holders. The product is a right‑hand thread with 14 mm nominal diameter and 1.5 mm pitch. It fits conventional round dienut/die stock holders and is driven and adjusted via the die stock clamping screws rather than an integrated drive end.

Typical applications include on‑site maintenance and workshop repair where studs and shafts require new or renewed external threads: general engineering, plant maintenance, automotive repair, agricultural machinery servicing, fabrication shops and HVAC installation. It is suitable for cutting threads in mild steel, aluminium, brass and many engineering plastics; harder or stainless materials should be cut with appropriate lubricants and conservative passes to avoid premature wear.

Key benefits of the M2 HSS construction are superior wear resistance and edge retention compared with carbon steel dies, and good thermal stability during cutting. The bright ground finish ensures accurate thread form, while the preservative oil reduces the risk of rust in storage. Compatibility with standard die stocks and adherence to ISO/British/DIN thread forms makes this dienut interchangeable with other metric tooling systems.

Duchy Fasteners carries a broad range of metric dienuts and die stocks: individual die nuts like this M14 × 1.5 are available as singles or in economy packs, and our stock covers common sizes from small metric threads up to larger diameters to suit workshop and on‑site needs.
