- Class 4h thread precision provides superior fit and vibration resistance, minimizing loosening in dynamic environments.
- Black-oxide coating on alloy steel offers enhanced corrosion resistance and durability, extending service life in harsh conditions.
- Integrated flange design distributes load evenly and improves seating stability, eliminating the need for separate washers.
- Rockwell C38 hardness delivers excellent wear resistance, maintaining thread integrity through repeated use.
- 12-point external drive allows for high-torque installation with standard tools, speeding up assembly processes.
- Fully threaded M8 coarse pitch ensures quick engagement and strong holding power in various materials.
Professional Applications & Engineering Value
These M8 12-point flange screws are engineered to address critical challenges in heavy-duty industrial settings, such as machinery assembly, automotive systems, and structural frameworks. The black-oxide alloy steel construction combats corrosion and wear, while the Class 4h thread fit ensures precise alignment and resistance to vibrational loosening—common issues in dynamic applications. The integrated flange enhances load distribution, preventing surface damage and improving joint integrity. With a coarse thread pitch of 1.25mm, these screws facilitate rapid installation and robust connections, making them ideal for time-sensitive projects requiring high-strength metric fasteners that endure rigorous operational demands.
Specification Summary & Compliance
This screw adheres to metric standards with an M8 x 1.25mm coarse thread and Class 4h thread fit for precise dimensional accuracy. It is manufactured from alloy steel with a black-oxide surface treatment, meeting industry requirements for durability. The product complies with relevant specifications for mechanical properties, including a tensile strength of 180,000 PSI and Rockwell C38 hardness, and is designed to align with general industrial standards such as RoHS and REACH for environmental safety.
