Product Description

The M14x120 Half Thread Bolt, also known as Partial Thread Hex Bolt M14 or External Hex Bolt M14x120, features a partially threaded shank design with a hex head for secure wrench engagement. This DIN 933-compliant fastener measures 120mm total length with a 14mm diameter, offering a 65mm threaded section and 55mm unthreaded shank for optimized load distribution. Constructed from Grade 8.8 carbon steel with optional zinc plating, it withstands tensile strengths up to 800 MPa and operates in -50°C to +150°C environments. Widely used in structural engineering, machinery assembly, and automotive applications, its partial threading reduces vibration loosening while maintaining shear strength. Key advantages include corrosion resistance and precise torque control, though the extended unthreaded portion may require specific joint thickness compatibility. The external hex design ensures compatibility with standard 21mm wrench sizes.
