Screw cylindrical head - hex DIN 912 M3x30-8.8

Product detailed description

The cylinder head screw with internal hexagon according to DIN 912, ISO 4762 and ČSN 021143 is designed for fixed screw connections with high preload. This component is ideal for applications where it is necessary to achieve high connection strength, while the assembly is carried out using an Allen key, which allows for easy and efficient handling.

The screw has a metric thread with a diameter of M3 and a total length of 30 mm. The head diameter is 5.5 mm, the head height is 3 mm and the width of the internal hexagon is 2.5 mm. The thread has a pitch of 0.50 mm and the thread length is 18 mm, which guarantees sufficient strength and stability in the connection.

It is made of steel of strength class 8.8, which means that it has high tensile strength and is suitable for demanding applications where high demands are placed on mechanical properties. The screw is supplied without surface treatment, but can be blackened, which provides basic corrosion protection and improves the aesthetic appearance.

This screw is suitable for a wide range of industrial applications, including mechanical engineering, automotive and construction, where it is necessary to ensure a reliable and permanent connection. Due to its design and material properties, it is ideal for use in environments where high mechanical and dynamic loads are required.
