Cast iron self-tapping screw DIN 939 M16x180-8.8

Product detailed description

The cast iron stud bolt according to DIN 939 with dimensions M16x180 is designed for applications requiring solid connections in blind holes. This component is made of steel and belongs to strength class 8.8, which means that it has a minimum yield strength of 640 MPa and a minimum tensile strength of 800 MPa. The bolt has a metric thread with a diameter of M16 and a pitch of 2.00 mm. The total length of the bolt is 180 mm, with the thread length at one end being 44 mm, which is intended for screwing into cast iron. The other end is shorter and serves for mounting the part.

The width c is 5 mm, the width e is 20 mm and the width a is 2.5 mm, which are critical dimensions for proper seating and function in the structure. The bolt has no surface treatment, which is important to consider when using it in an environment where corrosion may occur. The ČSN 21176 standard is equivalent to DIN 939, ensuring compatibility and interchangeability within European standards. This type of bolt is ideal for applications where it is necessary to ensure a reliable and strong connection in materials such as cast iron, while it is important to follow correct assembly procedures and take into account the mechanical properties of the material.
