Hexagon screw full thread DIN 961 M12x1.50x20-8.8 galvanized

Product detailed description

The screw with a hexagonal head and a fine metric thread according to DIN 961, ISO 8676 and ČSN 021103 is designed for applications requiring precise and strong connections. This screw has a diameter of M12 and a fine thread pitch of 1.50 mm, which allows for precise adjustment and higher joint strength compared to conventional metric threads. The total length of the screw is 20 mm.

The screw head is hexagonal with dimensions of the width between the surfaces (s) of 19 mm and the width between the diagonals (e) of 21.1 mm, which ensures easy handling using standard tools. The head height (k) is 7.5 mm, which provides sufficient space for the application of torque.

The screw material is steel of strength class 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 medium-duty mechanical applications where high strength and resistance to dynamic loads are required.

The surface treatment of the screw is white zinc-plated, which provides protection against corrosion and increases the life of the component in environments with moderate humidity. This treatment is suitable for both indoor and outdoor use, unless exposed to extreme corrosive conditions.

The screw is ideal for use in engineering and construction where high precision and strength of the connection is required. It is suitable for applications where fine-tuning of the connection is required, such as adjustment mechanisms or precision assembly assemblies.
