Product Description

The M12x55 hex bolt is a versatile half thread hex bolt designed for industrial applications requiring robust mechanical connections. This External hexagonal bolt M12 features a 55mm total length with partial threading, offering a threaded section for secure fastening and an unthreaded shank for enhanced shear resistance. Constructed from high-strength steel with a zinc-plated finish, it operates reliably in temperatures ranging from -40°C to +120°C. Ideal for machinery assembly, structural frameworks, and automotive components, its 12mm diameter hexagonal head enables high-torque installation using standard wrenches. Key advantages include corrosion resistance, 8.8 tensile strength rating, and vibration resistance due to the half-thread design, though its non-full threading limits depth adjustment flexibility in certain configurations. Compatible with M12 nuts and threaded receptacles across industrial equipment.
