Product Description

The M12x70 half thread hex bolt is a partial thread hex bolt designed with a 12mm nominal diameter and 70mm overall length, featuring a 35mm threaded section and 35mm smooth shank. It conforms to ISO 4014/DIN 931 standards, typically manufactured in grade 8.8 carbon steel or A4-70 stainless steel, with optional zinc plating or hot-dip galvanizing. This half threaded M12x70 hex bolt operates in temperatures ranging from -50°C to +300°C (material-dependent) and withstands tensile loads up to 800 MPa. Widely used in machinery assembly, structural engineering, and automotive applications, the M12x70 half thread hex bolt offers enhanced shear resistance in the unthreaded portion while maintaining adjustability. Key advantages include vibration resistance in fastened joints and precise length control, though installation requires proper alignment due to the partial threading. The bolt requires 19mm wrench size and demonstrates optimal performance in scenarios requiring combined clamping and bearing functions.
