Product Description

The M5x70 Hex Bolt, also recognized as the M5x70 Machine Screw or DIN 933 M5x70, is a precision-engineered fastening component designed for robust industrial applications. Featuring a 5mm thread diameter and 70mm length, it offers high tensile strength (typically ISO 898-1 Class 8.8 or higher) and corrosion resistance. Commonly integrated into machinery, automotive assemblies, and structural frameworks, this bolt ensures secure connections under demanding conditions, with a recommended torque range of 5-7 Nm. It operates reliably in temperatures from -30°C to +120°C and withstands vibration-heavy environments. Advantages include standardized compatibility (DIN 933), durability in harsh settings, and easy installation, while limitations involve potential thread wear with frequent disassembly. Ideal for high-stress mechanical systems requiring consistent performance.
