Screw ISO 7379-20-M16-55 Z041506

Cylindrical screw with hexagonal socket – reliable fastening

This ISO 7379-20-M16-55 screw is a solid connecting element, ideal for applications requiring high strength. Made of black oxidized steel, it is characterized by class 12.9, which guarantees its resistance to loads and long-term reliability. The cylindrical part with diameter d1 has been precisely ground, ensuring an accurate fit and stable connection.

Design and application

This screw, compliant with ISO 7379, is particularly useful in situations where a strong and durable threaded connection is needed. Its design with a hexagonal socket allows for easy assembly and disassembly using standard tools. The oxidized coating provides additional protection against corrosion, which is important in environments exposed to moisture or atmospheric factors.

Strength and parameters

Class 12.9 means that this screw has a high tensile strength – as much as 1200 N/m². This makes it perfect for applications exposed to high dynamic and static loads. Thread diameter M16 and length 55 mm make it a universal solution for many different industrial and construction applications. Precise execution of the cylindrical part guarantees accurate seating of the screw head in the fastened material, minimizing the risk of damage and ensuring an aesthetic appearance of the connection.
