Product Description

The M12x130 external hex bolt is a half-thread hex bolt featuring a partial thread design where the threaded portion spans a specific segment of the 130mm length, while the remaining shank remains unthreaded. Constructed from high-grade carbon steel with a zinc-plated finish, it offers corrosion resistance and a tensile strength rating of 8.8 or higher. This partial-thread hex bolt M12x130 is commonly used in heavy machinery, automotive assembly, and structural applications, providing secure fastening for components requiring adjustable clamping force. Key advantages include vibration resistance, simplified alignment during installation, and compatibility with standard hex tools. However, improper torque application may lead to thread stripping. The unthreaded section enhances shear strength, while the threaded portion allows precise tension control. Operating temperature ranges from -20°C to 120°C, suitable for most industrial environments. The M12x130 half-thread hex bolt excels in scenarios requiring combined load distribution and threaded adjustability.
