This product is a hexagonal die nut sized M35 x 1.5mm, a hand and machine cutting die designed to form or repair external ISO metric fine threads on round bars and shafts. It is used together with a compatible die stock (hand holder) or machine adapter to re-cut damaged threads or to create new M35 × 1.5 external threads on components during fabrication and maintenance.

The die is manufactured from M2 high‑speed steel (HSS), heat treated for cutting durability, and finished with a precision ground face to deliver an accurate thread form. The body is hexagonal to accept standard spanners or die stocks for tightening, and the internal profile cuts ISO metric fine threads with a 1.5mm pitch (conforming to ISO metric thread geometry). The product is manufactured to meet common metric thread standards including ISO 68‑1 and ISO 261, and is compatible with BS 3643 and DIN metric thread conventions when used with the correct alignment and cutting allowances.

M2 HSS provides good wear resistance and red hardness, so the die is suitable for cutting common steels, stainless steel, aluminium and non‑ferrous alloys when used with appropriate cutting fluid and correct technique. Typical applications include on‑site maintenance and repair of drive shafts, hydraulic fittings, plant and machine assembly, and toolroom thread production. Industries that commonly use this size and style include heavy engineering, plant maintenance, rail, petrochemical and fabrication workshops where large metric threads are required.

Key benefits of this hex die nut include the toughness and cutting life of M2 HSS compared with carbon steels, accurate reproduction of ISO metric fine thread form, and a serviceable hex body for secure holding in die stocks. The precision ground finish helps produce clean threads and reduces the likelihood of galling; using appropriate lubrication further improves surface quality and die life.
