Hexagon screw with toothed collar DIN 6921 M4x20-8.8 zinc
Code: 819803
Product detailed description
The DIN 6921 hexagon head screw with serrated collar, M4x20, is made of steel with a strength class of 8.8, which makes it suitable for use in applications requiring high strength and reliability. This screw is equipped with a metric thread with a pitch of 0.70 mm, while the total thread length is 20 mm, which corresponds to the total length of the screw.The hexagon head with serrated collar allows for efficient torque transmission and increases resistance to loosening, eliminating the need for a washer. In addition, the serrated collar increases friction between the screw and the mounting surface, ensuring joint stability.
The white zinc zinc coating provides corrosion protection, extending the life of the screw even in harsh conditions. The screw complies with EN 1665, which guarantees its compatibility and usability in a wide range of industrial applications.
This type of screw is ideal for mechanical connections in the automotive industry, engineering and other areas where high joint strength is required without the use of additional fasteners.
