Allen screw with centering hole DIN 6912 M4x12-8.8

Product detailed description

The Allen screw with a centering hole according to DIN 6912 is designed for applications where precise centering is required and where space is limited. This screw has a low cylindrical head with an internal hexagon, which allows for efficient torque transmission during assembly and disassembly using an Allen key.

The screw is made of steel of strength class 8.8, which indicates its high tensile strength and resistance to dynamic loads. Strength class 8.8 means that the minimum yield strength is 640 MPa and the minimum tensile strength is 800 MPa. The screw has no surface treatment, which is suitable for applications where increased corrosion resistance is not required.

The dimensions of the screw are as follows: metric thread M4 with a thread diameter of 4 mm and a pitch of 0.70 mm. The total thread length is 12 mm. The head diameter is 7 mm, the head height is 2.8 mm and the width of the Allen key groove is 3 mm. The 2 mm centering hole allows for precise positioning of the screw in the application.

This screw is ideal for use in mechanical assemblies where precision and reliability of connections are required, such as mechanical and electrical applications. It is suitable for assembly work where space for the screw head is limited and where it is necessary to ensure precise centering of components.
