- High tensile strength of 70,000 psi ensures reliable, secure fastening under demanding mechanical loads.
- Rockwell B55 hardness provides excellent durability and resistance to wear during installation and use.
- Class 6g thread fit with coarse pitch offers easy, precise assembly and reduced risk of cross-threading.
- Hex drive design (3 mm) allows for high-torque application with standard tools, minimizing slippage and damage.
- 90° countersink and flat head profile enables flush mounting for a clean, aerodynamic finish in assembled products.
- Full metric threading (M5 x 0.8 mm) ensures consistent engagement and holding power across various materials.
Professional Applications & Engineering Value
This M5 brass flat head screw is engineered to address common industrial fastening challenges, such as corrosion in humid or chemical-exposed settings. The brass construction naturally resists rust and galvanic corrosion, making it ideal for electrical enclosures, marine equipment, and plumbing systems. With a hex drive and coarse thread pitch, it simplifies installation in soft materials like wood or plastic, reducing assembly time and improving workflow efficiency. The fully threaded design and Class 6g fit provide uniform load distribution, preventing loosening under vibration—critical for machinery, automotive components, and precision instruments. Compliant with DIN 7991, it ensures interoperability and reliability in industrial applications requiring standardized metric fasteners.
Specification Summary & Compliance
This screw features precise metric threading (M5 x 0.8 mm) with a Class 6g thread fit per ISO standards, ensuring dimensional accuracy and compatibility. It meets DIN 7991 specifications for flat head hex drive screws, with a 90° countersink angle and fully threaded design. The product is RoHS 3 (2015/863/EU) compliant under exemption 6(a)-I for lead in brass alloys and REACH (EC 1907/2006) compliant, adhering to environmental and safety regulations for industrial use.
