Product Description

The Hex socket cap screw M6x65 is a high-precision Cylindrical socket head bolt compliant with DIN 7991 M6 screws standards. Crafted from grade 8.8 steel with a zinc-plated finish, it features a 6 mm diameter, 65 mm length, and a cylindrical head with a hexagonal socket (6 mm Allen key drive). Designed for industrial applications such as machinery assembly, automotive systems, and structural frameworks, these bolts offer high tensile strength (800 MPa), corrosion resistance, and vibration-proof clamping. Operating temperature ranges from -20°C to +120°C. Advantages include space-efficient installation and durability, while precise torque control (recommended 10 Nm) is critical to avoid stripping. Compliant with DIN 7991 specifications, they ensure reliable performance in high-stress environments.
