Key Features & Benefits at a Glance
- Superior corrosion resistance with black-phosphate steel coating, extending service life in harsh industrial environments.
- Exceptional load-bearing capacity due to Class 10.9 strength grade and 150,000 PSI tensile strength, ensuring reliable performance under high stress.
- Enhanced durability and wear resistance from Rockwell C32 hardness, reducing deformation and failure risks.
- Quick and secure installation with external hex drive and coarse 1.75mm pitch threads, minimizing assembly time and improving grip.
- Stable flange design with 26.6mm diameter, distributing load evenly and eliminating the need for separate washers.
- Precise thread fit (Class 6g) for consistent engagement and vibration resistance in dynamic applications.
- Full threading along the 40mm length provides maximum holding power and flexibility in various material thicknesses.
Professional Applications & Engineering Value
This M12 hex head screw is engineered to address critical challenges in heavy-duty industrial settings, such as machinery assembly, structural frameworks, and automotive components. The black-phosphate steel material offers excellent corrosion protection, reducing maintenance costs in humid or chemically aggressive environments. With a coarse thread pitch of 1.75mm and Class 10.9 strength, it ensures rapid installation and high clamping force, preventing loosening under vibration. The flanged head design enhances stability, making it ideal for applications requiring distributed load support without additional fasteners. Fully compliant with ASME B18.2.3.9M, it guarantees interoperability and safety in metric coarse thread systems, delivering reliable performance for engineers and procurement specialists.
Specification Summary & Compliance
This screw adheres to precise dimensional standards, including Class 6g thread fit for metric coarse threading and full compliance with ASME B18.2.3.9M specifications. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material sustainability. The product is manufactured to deliver consistent performance in industrial applications, with verified tensile strength and hardness metrics.
