Self-tapping screw for cast iron DIN 939 M24x140-8.8

Product detailed description

The cast iron stud bolt according to DIN 939 with dimensions M24x140 is designed for applications requiring solid connections in blind holes. This bolt is made of steel with strength class 8.8, which guarantees high mechanical resistance and reliability when used in harsh conditions. The surface treatment is not applied, which is suitable for applications where additional corrosion protection is not required.

The bolt design includes a metric thread with a diameter of M24 and a pitch of 3.00 mm. The total length of the bolt is 140 mm, while the thread length at the end intended for screwing into cast iron is 60 mm. This end is designed to provide optimal grip in the material, while the shorter thread at the opposite end is used for mounting other parts.

The width c is 7.5 mm, the width e is 30 mm and the width a is 3.8 mm, which are critical dimensions for the correct seating and function of the screw in the connection. The ČSN 21176 standard is equivalent to DIN 939, which guarantees compatibility and standardization within the European markets. The screw is ideal for use in mechanical engineering, where it is necessary to ensure strong and stable joints in cast iron components.
