Door screw DIN 603 M6x70 4.6 galvanized

Product detailed description

The DIN 603 M6x70 gate bolt is a structural element made of galvanized steel grade 4.6, which guarantees basic strength and corrosion resistance. This type of bolt is characterized by a flat hemispherical head and a square neck, which allows it to be used in applications where it is necessary to prevent the bolt from turning during installation. The DIN 603 standard, which is equivalent to ISO 8677 and ČSN 021319, defines the standards for this type of bolt, including dimensions and mechanical properties.

The diameter of the bolt is M6, which means that it has a metric thread with a nominal diameter of 6 mm. The length of the bolt is 70 mm, which makes it suitable for use in structures where a greater anchorage depth is required. The metric thread has a pitch of 1.00 mm, which is standard for this diameter and ensures compatibility with commonly used nuts and threaded holes.

The strength class 4.6 indicates that the screw has a minimum yield strength of 240 MPa and a minimum tensile strength of 400 MPa. The zinc coating provides protection against corrosion, which is important when used in outdoor or humid environments.

This screw is ideal for use in wooden structures, where it is often used to connect wooden elements such as beams and boards, but can also be used in other applications where a strong and stable connection is required.
