Screw cylindrical head - hex DIN 912 M4x65-8.8 galvanized
Code: 821031
Product detailed description
The screw with a cylindrical head and internal hexagon according to DIN 912, ISO 4762 and ČSN 021143 is intended for fixed screw connections with high preload. This component is suitable for assembly using an Allen key, which allows for precise and efficient tightening. The screw has a metric M4 thread with a length of 65 mm and a pitch of 0.70 mm.The cylindrical head of the screw has a diameter of 7 mm and a height of 4 mm, while the width of the internal hexagon is 3 mm, which corresponds to the standard dimensions for this type of screw. The thread length is 20 mm, which ensures sufficient grip in the material.
The screw material is steel of strength class 8.8, which provides high resistance to mechanical stress. The surface treatment is white zinc plating, which increases corrosion resistance and extends the service life of the component in various operating conditions.
This screw is ideal for applications requiring a reliable and strong connection, such as structural and engineering applications where precision and joint strength are important.
