Screw cylindrical head - hex DIN 912 M5x80-12.9

Product detailed description

The cylinder head screw with internal hexagon, marked according to DIN 912, ISO 4762 and ČSN 021143 standards, is intended for applications requiring fixed screw connections with high preload. This screw has a metric M5 thread with a length of 80 mm and a pitch of 0.80 mm. The head diameter is 8.5 mm, the head height is 5 mm and the width of the internal hexagon is 4 mm, which allows assembly using an Allen key.

The screw is made of steel with a strength class of 12.9, which means that it has a high tensile strength, namely a minimum yield strength of 1080 MPa and a minimum tensile strength of 1220 MPa. This type of steel is suitable for applications where high mechanical resistance is required. The screw is supplied uncoated or blackened, which may be important for applications where basic corrosion protection or aesthetic requirements are required.

The thread length is 22 mm, which allows sufficient engagement in the material, while the remaining part of the screw provides the necessary length for specific design requirements. This screw is ideal for use in engineering and construction where it is necessary to ensure a reliable and strong connection of components.
