Self-tapping screw for cast iron DIN 939 M8x35 stainless steel A2

Product detailed description

The DIN 939 cast iron stud bolt with dimensions M8x35 is designed for applications requiring a strong and reliable connection in blind holes. This component is made of A2 grade stainless steel, which provides high corrosion resistance and is suitable for use in environments with higher humidity or chemical exposure. A2 stainless steel is commonly used in industrial and construction applications where long-term durability and reliability of connections are required.

The screw has a metric thread with a diameter of M8 and a pitch of 1.25 mm. The total length of the screw is 35 mm, while the length of the thread at the longer end, intended for screwing into cast iron, is 22 mm. This design allows for effective force distribution and a firm hold in the material, minimizing the risk of loosening or damage to the connection. The shorter thread is designed for mounting the part, which allows easy installation and removal without the need to access the back of the joint.

The width c is 3.2 mm, the width e is 10 mm and the width a is 1.6 mm, which are critical dimensions for the correct fit and functionality of the screw within the structural unit. This screw is supplied without surface treatment, which is typical for stainless steel materials that naturally resist corrosion. The ČSN 21176 standard is equivalent to the DIN 939 standard, which guarantees compatibility and interchangeability within international standards.
