Flat set screw - hex DIN 913 M8x20 galvanized

Product detailed description

The set screw with a flat end and internal hexagon according to DIN 913, ISO 4026 and ČSN 021187 is designed for precise and secure locking of parts without damaging the seating surface. This screw has a metric thread with a diameter of M8 and a length of 20 mm, with a thread pitch of 1.25 mm. The head diameter is 5.5 mm and the width of the internal hexagon is 4 mm, which allows the use of a standard Allen key for easy assembly and disassembly.

The screw is made of steel of strength class 45H, which guarantees high resistance to mechanical stress. The zinc coating provides additional protection against corrosion, thus extending the service life of the component even in more demanding conditions. This treatment is carried out with white zinc, which is commonly used for its anti-corrosion properties and aesthetic appearance.

The use of this set screw is wide, especially in engineering and industry, where precise adjustment and fixation of components is required without the risk of surface damage. The internal hexagon allows for efficient torque transmission, which increases the reliability of the connection. The screw is ideal for applications where repeated assembly and disassembly are required, while maintaining its mechanical properties and functionality.
