Allen screw with centering hole DIN 6912 M8x40-8.8 galvanized

Product detailed description

The Allen screw with centering hole according to DIN 6912 is designed for applications where precise centering is required and where space for assembly is limited. This screw has a metric M8 thread with a length of 40 mm, with a thread pitch of 1.25 mm. The total thread length is 22 mm, which allows sufficient grip in the material.

The screw head is a low cylindrical one with an internal hexagon, which allows the use of an Allen key for assembly and disassembly. The head diameter is 13 mm, the head height is 5 mm and the key width (B1) is 6 mm. The centering hole with a diameter of 4 mm ensures precise centering of the screw in the application.

The screw material is steel of strength class 8.8, which means that it has a minimum yield strength of 640 MPa and a minimum tensile strength of 800 MPa. The surface treatment is white zinc plating, which provides corrosion protection and increases the resistance of the screw in environments with higher humidity or chemical aggressiveness.

This screw is ideal for use in mechanical engineering, where reliable and precise connection of components with limited mounting space is required, as well as in applications where corrosion protection is important.
