Door screw DIN 603 M10x90 8.8 galvanized

Product detailed description

The DIN 603 M10x90 8.8 galvanized gate bolt is a structural element designed for the firm connection of materials, characterized by its flat hemispherical head and square neck. This type of bolt is manufactured according to the DIN 603 standard, which is equivalent to the ISO 8677 and ČSN 021319 standards. The bolt has a metric thread with a diameter of M10 and a length of 90 mm, with a thread pitch of 1.50 mm.

The material of the bolt is steel with a strength class of 8.8, which means that it has a minimum yield strength of 640 MPa and a minimum tensile strength of 800 MPa. This strength class is suitable for applications where higher mechanical resistance is required. The surface treatment is zinc-plated, specifically white zinc, which provides corrosion protection and increases the life of the component in environments with normal humidity.

The screw is designed so that the square neck is recessed into the material during installation, preventing it from turning while the nut is tightened. This design is particularly useful in the woodworking and construction industries, where it is often used to connect wooden structures or to fasten metal elements to wood. The screw is used in applications where aesthetic surface treatment is required, as its head remains visible after installation, providing a smooth and clean appearance.
