Screw cylindrical head - hex DIN 912 M12x80-12.9

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 ideal for applications where high joint strength and reliability are required. The screw has a metric thread with a diameter of M12 and a pitch of 1.75 mm, which allows it to be used in a wide range of industrial applications.

The cylinder head of the screw has a diameter of 18 mm and a height of 12 mm, while the internal hexagon allows assembly using an Allen key, which ensures simple and effective assembly even in limited spaces. The width B1 is 10 mm, which contributes to the optimal distribution of forces during tightening. The thread length is 36 mm, which provides sufficient depth for secure attachment in the material.

The material of the screw is steel with a strength class of 12.9, which means that the screw has a high tensile strength and is suitable for demanding mechanical applications. The strength class of 12.9 indicates a minimum yield strength of 1080 MPa and a minimum tensile strength of 1220 MPa. The screw is supplied without surface treatment, which is suitable for applications where corrosion protection is not required, or where additional surface treatment is planned according to specific project requirements.

This screw is suitable for use in various industrial sectors, including mechanical engineering, automotive and construction, where high strength and reliability of joints are required.
