- Superior corrosion resistance from the black-phosphate steel coating extends service life in harsh industrial environments.
- Integrated DIN 6921 flange distributes load evenly, minimizing surface damage and providing a secure, vibration-resistant connection.
- Class 10.9 strength grade and Rockwell C32 hardness offer high durability and resistance to wear and deformation.
- Coarse M6x1 mm thread with Class 6g fit enables quick and easy installation, saving assembly time while maintaining precision.
- Partially threaded design allows for controlled clamping force, ideal for applications requiring precise joint security.
- External hex drive ensures straightforward installation with standard tools, enhancing efficiency in maintenance and production.
Professional Applications & Engineering Value
Engineered for demanding industrial settings, these M6 hex head screws with black-phosphate steel construction address common challenges like corrosion and mechanical stress. The DIN 6921 flanged design eliminates the need for separate washers, reducing assembly parts and preventing loosening under vibration. With a coarse thread pitch and partial threading, they provide optimal grip in materials such as metal and hardened plastics, making them ideal for machinery, automotive assemblies, and structural frameworks. This combination of high tensile strength and corrosion resistance ensures long-term reliability, minimizing downtime and maintenance costs in heavy-duty applications.
Specification Summary & Compliance
This screw adheres to ISO 898-1 standards with a Class 6g thread fit for precise dimensional accuracy. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring environmental safety and regulatory alignment for global industrial use.
