Screw cylindrical head - hex DIN 912 M5x220-12.9

Product detailed description

The cylinder head screw with internal hexagon according to DIN 912, ISO 4762 and ČSN 021143 is designed for applications requiring strong screw connections with high preload. This screw has a metric thread M5 and a length of 220 mm. It is made of steel of strength class 12.9, which means that it has high tensile strength and is suitable for demanding mechanical applications. Strength class 12.9 indicates a minimum yield strength of 1080 MPa and a minimum tensile strength of 1220 MPa, which makes it ideal for use in structures where high demands are placed on mechanical resistance and reliability.

The screw head is cylindrical in shape with an internal hexagon, which allows the use of an Allen key for assembly and disassembly. This design provides efficient torque transmission and minimizes the risk of head damage when tightening. The screw is uncoated, meaning it is in a basic blackened condition, making it suitable for applications where additional corrosion protection is not required.

This screw is suitable for use in a variety of industries including mechanical engineering, automotive and equipment manufacturing, where a strong and reliable connection of components is required. It is important to consider the environmental conditions in which the screw will be used, particularly if it is exposed to corrosive environments where additional surface treatment may be required.
