Screw cylindrical head - hex DIN 912 M3x12-8.8 galvanized

Product detailed description

The cylinder head screw with internal hexagon, also known as an inbus, is manufactured according to DIN 912, ISO 4762 and ČSN 021143 standards. This component is designed for fixed screw connections with high preload, which means that it is ideal for applications where it is necessary to ensure high reliability and strength of the connection. The screw has a metric thread with a diameter of M3 and a pitch of 0.50 mm, which is a standard size for this type of fastener.

The screw head has a cylindrical shape with a diameter of 5.5 mm and a height of 3 mm, while the internal hexagon allows assembly using an Allen key. This type of head is popular for its compact dimensions and ability to transmit high torques without damaging the screw head.

The screw is made of steel of strength class 8.8, which means that it has high tensile strength and is suitable for demanding mechanical applications. The surface treatment is white zinc plating, which provides protection against corrosion and increases resistance to external influences. The total thread length is 12 mm, which allows sufficient anchoring in the material.

This type of screw is widely used in mechanical engineering, the automotive industry and other technical areas where it is necessary to ensure a reliable and strong connection of components.
