Description

Description

The M4 x 30 8.8 zinc-plated hexagon head bolt, DIN 933 represents a versatile fastener for engineering and maintenance. Thanks to the full thread from head to tip, it allows for flexible tightening of assembled components.

Property class 8.8 provides sufficient tensile and shear strength for standard industrial applications. In addition, the zinc-plated finish protects the bolt from atmospheric moisture and light corrosive environments.

Key Features and Specifications

  • Dimensions: M4 thread with a length of 30 mm and a 7 mm wrench size for precise and secure installation.
  • Fully threaded (DIN 933 / ISO 4017): Allows for a secure connection of materials even in places where precision clearance holes cannot be used.
  • Property class 8.8: Guarantees high resistance to mechanical stress in machinery assemblies.
  • Surface treatment: The zinc layer extends the overall lifespan of the joint and facilitates its potential future disassembly.

During installation, ensure the correct tightening torque corresponding to class 8.8 is used to prevent thread stripping. For permanent outdoor applications, we recommend considering additional anti-corrosion protection for the assembled joint.
