Product Description

The M10-70 hex bolt is a metric hex head screw designed with an external hex flange for secure fastening in industrial applications. This external hex flange bolt features a 10mm diameter and 70mm length, complying with ISO/DIN standards, and is typically constructed from high-grade steel (Grade 8.8/10.9) with optional zinc or galvanized coatings for corrosion resistance. It operates effectively in temperature ranges of -50°C to +150°C, suitable for automotive, machinery, and construction industries. The flange design eliminates separate washers, ensuring even load distribution and vibration resistance. Advantages include robust durability and simplified assembly, while potential drawbacks include limited compatibility with non-metric systems. Its hexagonal head allows standard wrench installation, supporting torque values up to 47 Nm (Grade 8.8). Ideal for heavy-duty structural joints or equipment requiring high shear strength.
