Screw ISO 7379-16-M12-45 Z041492

Fitted screw with collar – solid mounting in many applications

The ISO 7379-16-M12-45 screw is a fastener made of high-strength steel, ideal for applications requiring a secure and durable connection. It is characterized by class 12.9, which means a tensile strength of 1200 N/mm². The black oxidized surface provides basic corrosion protection.

Design and characteristics

The design of this screw distinguishes it from standard fasteners. It has a rolled d1 section, which has been precisely ground. This process affects dimensional accuracy and ensures stable seating in the hole. This screw is particularly useful where precision and minimizing play are important. It is worth noting the geometry of the screw head – a small bearing surface and undercutting affect the maximum tightening torque, which is not determined solely by the material strength class.

Application and benefits

Fitted screws ISO 7379 are widely used in various industries, including:

• Mechanical engineering: Mounting structural elements of machines and equipment.
• Automation: Assembly of industrial automation components.
• Construction: Connections in steel structures (taking into account tightening torque limitations).
• General industry: Universal mounting of elements requiring precise positioning.

Thanks to its high strength and precise workmanship, this screw guarantees a reliable connection even in difficult operating conditions. The ground shank minimizes the risk of damage to mating parts during assembly.
