Product Description

The M12x150 half thread hex bolt is a partial thread hexagonal bolt designed with an external hex head for secure fastening applications. This External hex head bolt M12 features a total length of 150mm, combining a 75mm threaded section (ISO metric coarse thread) and 75mm unthreaded shank, optimized for vibration resistance. Crafted from grade 8.8 steel with zinc-plated finish, it operates within -50°C to +120°C environments, suitable for machinery, structural engineering, and automotive assembly. The hex head accepts 19mm wrench size, providing 900MPa tensile strength and 640MPa yield strength. Advantages include enhanced shear resistance in unthreaded zones and simplified alignment, though precise thread engagement measurement is crucial during installation. This partial thread hexagonal bolt 150mm complies with DIN 933 standards, offering corrosion protection for outdoor applications but requires periodic inspection in high-humidity conditions.
