Cylinder head socket screw M6x20 black 12.9, DIN912

The high-tensile socket head cap screw M6x20 black 12.9, DIN912 represents a reliable fastening element for your most demanding engineering and structural applications. Thanks to the 12.9 strength class, it safely resists extreme tension and shear, giving you the assurance of long-term joint stability even under high dynamic loads.

This model features a full M6 thread with a length of 20 mm and a cylindrical head with an internal hexagon, which allows for firm fastening even in very tight assembly spaces. Due to the absence of surface treatment, the screw comes in a basic black finish, which is advisable to consider during design in terms of corrosion protection.

Technical Advantages and Details

• Hexagon socket (allen): Mounted using a 5 mm size key, which prevents rounding of the edges and ensures excellent transmission of tightening torque. The head height is 6 mm.
• Full M6x20 thread: Provides maximum clamping reliability along the entire length of the screw shank.
• Extreme 12.9 strength: Guarantees excellent mechanical properties for the most stressed components of machines and clamping fixtures.
• Standardization DIN 912 / ISO 4762: Strict adherence to standards facilitates compatibility and easy replacement of parts during maintenance.

During installation, always make sure to observe the correct prescribed tightening torque for strength class 12.9 in order to fully utilize the strength potential of the joint. If the mechanism is to be exposed to increased humidity, we recommend additionally treating it with a protective lubricant to maintain a long service life.
