Product Description

The M12x70 hex bolt, a Metric external hex bolt, features a standard M12 hex head bolt 70mm in length designed for robust mechanical fastening applications. Manufactured with a thread diameter of 12mm and a shank length of 70mm, this bolt is compatible with ISO metric standards (e.g., DIN 933/931) and typically made from high-tensile steel (grade 8.8 or higher) or corrosion-resistant stainless steel (A2/A4). It operates in temperature ranges from -50°C to +150°C and is commonly used in construction, automotive, and industrial machinery for structural assembly. Key advantages include its standardized hex head for easy torque application, high load-bearing capacity, and durability under harsh conditions. Potential drawbacks involve alignment sensitivity in high-vibration environments. Surface finishes like zinc plating or hot-dip galvanizing enhance rust resistance.
