Screw cylindrical head - hex DIN 912 M4x10-12.9

Product detailed description

The cylinder head screw with internal hexagon according to DIN 912, ISO 4762 and ČSN 021143 standards is intended for fixed screw connections with high preload. This component is designed for use with an Allen key, which allows efficient assembly and disassembly in limited spaces. The screw has a metric thread with a diameter of M4 and a pitch of 0.70 mm, while the total thread length is 10 mm. The cylinder head has a diameter of 7 mm and a height of 4 mm, which provides sufficient space for the application of torque.

The screw material is steel of strength class 12.9, which indicates high tensile strength and resistance to mechanical stress. This strength class is suitable for applications where high reliability and resistance to dynamic loads are required. The screw is supplied without surface treatment, which means that its surface is blackened, providing basic protection against corrosion.

This type of screw is ideal for use in mechanical engineering, the automotive industry and other areas where reliable and strong screw connections are required. Thanks to the internal hexagon, it is possible to achieve higher torque without the risk of damaging the screw head, which is especially important in applications with high mechanical loads.
