Product Description

The M12x140 hex bolt half thread is a partially threaded external hex head bolt designed for industrial fastening applications. This External hex head bolt M12-140 features a nominal diameter of 12mm, 140mm total length, with a threaded portion covering approximately 60% of the shank. The partially threaded M12x140 hex bolt offers enhanced grip strength in machinery assembly, automotive components, and structural frameworks, compatible with standard M12 nuts. Engineered from grade 8.8 carbon steel, it operates in -50°C to +150°C environments with zinc-plated corrosion resistance. Advantages include wrench-friendly external hex design for high torque transmission and optimized load distribution through partial threading, though the reduced threaded area limits full-length adjustment capabilities. Typical industrial applications involve heavy equipment mounting, chassis construction, and hydraulic system installations requiring vibration resistance.
