Allen screw with centering hole DIN 6912 M12x70-8.8

Product detailed description

The Allen screw with centering hole according to DIN 6912 is a specific type of fastener designed for applications with limited space and a requirement for precise centering. This component has a low cylindrical head with an internal hexagon, which allows for efficient torque transmission during assembly and disassembly. The internal hexagon is often referred to as an inbus, which is an abbreviation for "Innensechskantschraube", i.e. a screw with an internal hexagon.

The screw has a metric M12 thread with a diameter of 12 mm and a thread pitch of 1.75 mm. The total length of the screw is 70 mm, with a thread length of 30 mm. The head diameter is 18 mm and its height is 7.5 mm, which meets the requirements for a low head that minimizes the height above the surface. The diameter of the centering hole is 6 mm, which allows for precise centering of the screw during assembly.

The material of the screw 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 screw is supplied without surface treatment, which is suitable for applications where additional corrosion protection or aesthetic requirements are not required.

This type of screw is ideal for use in engineering and construction, where a reliable and precise connection is required in limited space. Thanks to its design and material properties, it provides high strength and resistance to mechanical stress.
