Screw cylindrical head - hex DIN 912 M8x140-12.9

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 suitable for assembly using an Allen key, which allows for efficient torque transmission and ensures a reliable connection.

The screw has a metric M8 thread with a diameter of 8 mm and a pitch of 1.25 mm, while the total length of the screw is 140 mm. The thread length is 28 mm, which provides sufficient surface area for fastening in the material. The cylinder head has a diameter of 13 mm and a height of 8 mm, while the internal hexagon has a width of 6 mm, which is a standard size for this type of screw.

The screw material is high-quality steel with a strength class of 12.9, which means that the screw has high tensile strength and is able to withstand significant mechanical loads. The screw is supplied without surface treatment, but can be blackened, which provides basic corrosion protection and improves the aesthetic appearance.

This screw is ideal for use in applications where high preload is required and where strength and reliability are critical. It is suitable for industrial applications, engineering and construction, where it is necessary to ensure a strong and permanent connection of components.
