Description

M8x80 countersunk socket head screw, black, 10.9, DIN7991 is a high-strength fastener for applications where you need to hide the screw head flush with the surface. With an overall length of 80 mm and a partial thread length of 22 mm, it provides reliable clamping in places where the protruding head of a standard screw would interfere with operation.

Thanks to the high strength class 10.9, this screw is designed for joints with high mechanical stress. The absence of surface treatment (the so-called black finish) requires additional protection outdoors or in aggressive environments, but under normal conditions in engineering operations, it will ensure an extremely stable and secure joint.

Key Features and Parameters

Countersunk head (height 4 mm): Allows precise flush mounting with the surface and prevents catching on moving machine parts.
Hexagon socket (allen key size 5 mm): Facilitates safe installation and tightening even in tight spaces.
Partial thread: The 22 mm long thread helps to efficiently and forcefully clamp the joined materials together.
Standardization DIN 7991 / ISO 10642: Guarantees precise dimensions and easy interchangeability for your repairs.

During installation, ensure the correct angle and depth of the countersink to achieve a perfectly flat surface. Adhering to the recommended tightening torque will help extend the lifespan of the entire engineering assembly.
