Screw cylindrical head - groove DIN 84 M3x55 galvanized

Product detailed description

The cylinder head screw with a straight groove according to DIN 84, ISO 1207 and ČSN 021131 is intended for precision assemblies in mechanical engineering and electrical engineering, where a strong and reliable connection is required. This screw has a metric thread with a diameter of M3 and a length of 55 mm, with a thread pitch of 0.50 mm. The cylinder head has a diameter of 5.5 mm and a height of 2 mm, which ensures sufficient surface area for applying torque using a tool with a straight groove, the width of which is 0.8 mm.

The screw material is steel with a strength class of 4.8, which means that it has a yield strength of 320 MPa and a tensile strength of 400 MPa. The surface treatment is made using white zinc, which provides increased corrosion resistance, thereby extending the service life of the component in harsh conditions. The screw is suitable for applications where high precision and reliability of the connection are required, while its design features allow for use in a wide range of technical equipment and structures.
