Screw ISO 7379-10-M8-65 Z041477

Flange screws, such as this one, are widely used in machines and equipment where a strong and secure connection is required. Made of black oxidized steel, they offer not only durability but also corrosion resistance. Class 12.9 guarantees high tensile strength – up to 1200 N/m2 – making them ideal for heavily loaded applications.

This specific screw, designated as ISO 7379-10-M8-65, has an M8 thread diameter and a length of 65 mm. The cylindrical part with diameter d1 has been precisely ground, ensuring a precise fit and connection stability. This is important for installers who value precision and end-users who expect reliability and safety.

Design and application

ISO 7379 flange screws are particularly useful in situations where a large bearing surface is needed or when increased connection stability is required. The flange distributes the pressure over a larger area, minimizing the risk of damage to the joined components. This makes them ideal for mounting machine elements, industrial equipment, and steel structures. The ground cylindrical part ensures accurate seating of the screw in the hole, which translates to precise assembly and minimizes the risk of loosening during operation.

Choosing the right screw

When choosing a flange screw, it is worth paying attention to its strength class and the material it is made of. Class 12.9 provides the highest strength among commonly available screw classes. Black oxidized steel is a good compromise between strength and corrosion resistance – especially in indoor or dry environments. For applications exposed to moisture or aggressive chemicals, it is recommended to use screws made of stainless steel or coated with additional protective layers.
