Allen screw with centering hole DIN 6912 M8x80-8.8 galvanized

Product detailed description

The DIN 6912 Allen screw with centering hole is designed for applications where precise centering is required and limited mounting space is required. This screw has a low cylindrical head with an internal hexagon, which allows it to be used in situations where the head height is critical. The internal hexagon provides efficient torque transmission, increasing the reliability of the connection.

The screw has a metric thread with a diameter of M8 and a pitch of 1.25 mm, which is the standard for this type of fastener. The screw length is 80 mm, while the thread length is 22 mm. The head diameter is 13 mm, the width B1 is 6 mm and the head height H is 5 mm, which are important dimensions to ensure correct seating in the structure. The diameter of the centering hole is 4 mm, which allows for precise centering of the screw in the mounting hole.

The screw material is steel with a strength class of 8.8, which means that the screw has high tensile strength and is suitable for demanding mechanical applications. The surface treatment is white zinc plating, which provides corrosion protection and increases the life of the screw in environments with higher humidity or chemical exposure.

This screw is ideal for use in mechanical engineering, where reliable and precise connection of components with limited dimensions and a requirement for precise centering is required. It is suitable for applications where it is necessary to minimize the head height while ensuring high strength and corrosion resistance.
