Screw ISO 7379-10-M8-55 Z041476

Cylindrical screw with hexagonal socket – strength and precision

This ISO 7379-10-M8-55 screw is a solid fastening element, made of black oxidized steel, providing good corrosion resistance. Class 12.9 guarantees high tensile strength – up to 1200 N/m2 – making it ideal for applications requiring a reliable connection. This screw is particularly valued in machine constructions, devices and all kinds of assemblies where certainty and durability are important.

Design and application

The screw has a cylindrical head with a hexagonal socket, allowing for fastening with a flat or socket wrench. The cylindrical part with diameter d1 has been ground, which ensures a precise fit and connection stability. This design minimizes the risk of damage to cooperating elements during assembly. These types of screws are widely used in the mechanical industry, automotive and in machine construction.

Key features and benefits

• High strength: Class 12.9 provides resistance to static and dynamic loads, which translates into long-term connection reliability.
• Precise workmanship: Ground cylindrical part guarantees accurate fit and assembly stability.
• Corrosion resistance: Oxidized surface increases resistance to environmental factors.
• Versatility: The screw finds application in many industries and types of construction.
• Easy assembly: Hexagonal socket enables quick and convenient assembly with standard tools.
• ISO 7379 compliant: Guarantee of quality and dimensions in accordance with international standard.

These types of screws are often used where high connection precision and resistance to loads are required – from simple assemblies to complex machine constructions. Choosing a class 12.9 screw is an investment in the safety and durability of your projects.
