Product Description

The M8x60 hex bolt is a half thread hex bolt featuring an external hex head design, engineered for secure fastening in structural and mechanical applications. With a total length of 60mm, it combines a 30mm threaded section and 30mm smooth shank, offering balanced grip strength and alignment precision. Manufactured from grade 8.8 carbon steel with optional zinc plating, it withstands working temperatures from -20°C to 120°C and operates under typical mechanical loads up to 640MPa. This external hex head bolt excels in automotive assembly, machinery production, and electrical enclosure installations due to its corrosion resistance and tool compatibility with standard 13mm wrenches. While ideal for permanent installations, its half-thread configuration limits adjustment flexibility compared to fully threaded variants. The bolt's hexagonal profile ensures anti-slip torque transmission and accommodates vibration-prone environments when paired with locking washers.
