Cast iron self-tapping screw DIN 939 M20x45-8.8

Product detailed description

The cast iron stud bolt according to DIN 939 with dimensions M20x45 is designed for fixed connections in blind holes. This component is made of steel with strength class 8.8, which guarantees high resistance to mechanical stress and is suitable for applications where high joint strength is required. The screw has no surface treatment, which means that it is suitable for use in environments where corrosion protection is not required or where additional surface treatment is planned according to specific project requirements.

The stud bolt has a metric thread with a diameter of M20 and a pitch of 2.50 mm, which is a standard thread for this type of component. The total length of the screw is 45 mm, while the thread length is 38 mm, which allows for fixed screwing into cast iron. The thread is on both ends, with the longer thread intended for screwing into cast iron and the shorter for mounting the part. The width c is 6.3 mm, the width e is 25 mm and the width a is 3.2 mm, which are important dimensions for precise fitting and assembly.

This screw is ideal for use in structures where it is necessary to ensure a strong and reliable connection in blind holes, especially in applications where cast iron is used as the base material. It is suitable for various industries, including mechanical engineering and equipment manufacturing, where precision and reliability of connections are important.
