Door screw DIN 603 M6x90 4.6 galvanized

Product detailed description

The DIN 603 M6x90 carriage bolt is designed for applications where it is necessary to ensure a solid connection with the possibility of concealed fastening. This bolt is made of steel of strength class 4.6, which means that it has a yield strength of 240 MPa and a tensile strength of 400 MPa. The surface treatment is made with white zinc plating, which provides protection against corrosion and increases resistance to external influences.

The design of the bolt includes a flat hemispherical head with a square neck, which corresponds to the standards DIN 603, ISO 8677 and ČSN 021319. This design allows the bolt to be automatically fixed against rotation after being inserted into the hole, which facilitates assembly and increases the stability of the joint. The square neck cuts into the material, preventing the screw from rotating when the nut is tightened.

The thread diameter is M6 with a metric thread type and a pitch of 1.00 mm, which is standard for this size. The length of the screw is 90 mm, which makes it suitable for use in applications where it is necessary to overcome greater material thickness or provide sufficient length to hold the nut.

This screw is suitable for use in the woodworking industry, when assembling wooden structures, fences or other applications where it is necessary to ensure a strong and reliable connection. Thanks to its design and surface treatment, it is also suitable for outdoor use where it is exposed to weather conditions.
