Screw cylindrical head - hex DIN 912 M30x80-8.8 galvanized

Product detailed description

The hexagon socket head cap screw, also known as the Allen screw, is manufactured according to DIN 912, which is equivalent to the international standards ISO 4762 and ČSN 021143. This screw has a thread diameter of M30 and a length of 80 mm, which makes it suitable for use in applications where it is necessary to ensure strong and reliable screw connections with high preload.

The material of the screw is steel of strength class 8.8, which means that it has a minimum yield strength of 640 MPa and a minimum tensile strength of 800 MPa. This strength class is suitable for applications where high strength and resistance to mechanical stress are required. The surface treatment of the screw is galvanic zinc plating, which provides protection against corrosion and increases its resistance in difficult operating conditions.

The cylindrical head of the screw allows for effective force transmission and ensures even pressure distribution on the surface to which the screw is fastened. The internal hexagon (hexagon) allows assembly and disassembly using an Allen key, which is practical in confined spaces where traditional tools cannot be used. The screw is ideal for use in mechanical engineering, construction and other industries where high demands are placed on the reliability and durability of connections.
