Screw cylindrical head - hex DIN 912 M12x1.25x35-12.9

Product detailed description

The cylinder head screw with internal hexagon according to DIN 912, ISO 4762 and ČSN 021143 is designed for precise and strong connections in mechanical engineering. This screw has a metric thread with a fine pitch M12x1.25 and a length of 35 mm, which makes it an ideal choice for applications requiring high precision and strength of connections.

It is made of steel of strength class 12.9, which means that it has a high tensile strength, namely at least 1200 MPa, and a yield strength of at least 1080 MPa. This strength class is suitable for applications where high mechanical resistance is required. The screw is supplied without surface treatment, which means that it is not protected against corrosion and is suitable for use in environments where it is not exposed to corrosive influences, or where additional surface treatment is planned according to specific application requirements.

The cylindrical head with an internal hexagon allows for efficient torque transmission during assembly and disassembly, while the internal hexagon (inbus) ensures secure tool attachment and minimizes the risk of head damage when applying higher torques. The screw is ideal for use in mechanical engineering where high-strength and precision joints are required, such as in the automotive industry, in the manufacture of machinery and equipment, or in other technical applications requiring reliable and durable fasteners.
