Screw cylindrical head - hex DIN 912 M5x140-8.8

Product detailed description

The cylinder head screw with internal hexagon according to DIN 912, ISO 4762 and ČSN 021143 is designed for fixed screw connections with high preload. This screw is suitable for assembly using an Allen key, which allows for efficient torque transmission and ensures reliable tightening.

The screw has a metric thread with a diameter of M5 and a length of 140 mm. It is made of steel with a strength class of 8.8, which means that it has a minimum yield strength of 640 MPa and a minimum tensile strength of 800 MPa. This material is suitable for applications where high strength and resistance to mechanical stress are required. The screw is not surface-treated, which means it is in a blackened state, and is therefore suitable for use in environments where increased corrosion resistance is not required.

The cylindrical head of the screw allows it to be used in applications where the head needs to be recessed into the material, thus achieving an aesthetic appearance and minimizing the risk of catching on protruding parts. The internal hexagon (hexagon) provides easy access for tools and allows the application of higher torque without the risk of damaging the screw head.

This screw is ideal for use in engineering, construction and applications where high joint strength and assembly accuracy are required. It is suitable for use in dry environments or where additional corrosion protection is provided.
