Product detailed description

The cast iron stud bolt according to DIN 939 with dimensions M20x80 and strength class 8.8 is designed to create solid connections in blind holes. This component is made of steel, which guarantees high strength and resistance to mechanical stress. The bolt has a metric thread with a diameter of M20 and a pitch of 2.50 mm. The total length of the bolt is 80 mm, while the thread length is 46 mm.

The design of the bolt includes a thread at both ends, with one end being longer and intended for screwing into cast iron, while the shorter end is used for mounting the connected part. The width c is 6.3 mm, the width e is 25 mm and the width a is 3.2 mm. The bolt has no surface treatment, which means that it is without additional corrosion protection.

This screw is ideal for applications where it is necessary to ensure a strong and reliable connection in cast iron materials, while it is important to take into account the absence of surface treatment when used in environments with higher humidity or chemical aggressiveness. The screw meets the standards DIN 939 and ČSN 21176, which guarantees its compatibility and standardized dimensions for industrial applications.
