Self-tapping screw for cast iron DIN 939 M12x55-8.8 galvanized

Product detailed description

The DIN 939 cast iron stud bolt is designed for applications requiring solid connections in blind holes. This particular model has a metric M12 thread and an overall length of 55 mm. The screw is made of steel with a strength class of 8.8, which guarantees high resistance to mechanical stress and is suitable for use in structures where high demands are placed on the strength of the connection.

The stud bolt has a thread at both ends, with the longer thread with a length of 30 mm intended for screwing into cast iron, while the shorter thread is used for mounting the connected part. The thread has a pitch of 1.75 mm, which is standard for metric threads of this size. The surface treatment is zinc-plated, which provides protection against corrosion and increases the service life of the component in harsh conditions.

The dimensions of the screw include a width of c 4.3 mm, a width of e 15 mm and a width of a 2.2 mm, which are important parameters for precise fitting and assembly. The screw is suitable for use in various industrial applications where reliable fixation of components in cast iron materials is required. The white zinc coating ensures not only an aesthetic appearance, but also increased resistance to external influences.
