Product Description

The metric hex bolts M8x55, conforming to DIN 933 M8-55 bolt and ISO 4014 hex head screw standards, feature a full-threaded shank with a 55mm length and M8 nominal diameter. These fasteners are engineered for high tensile strength (typically graded 8.8 or higher) and corrosion resistance through zinc plating or hot-dip galvanization. Commonly used in mechanical assembly, automotive manufacturing, and structural applications, their hexagonal head design enables secure torque transmission using standard 13mm wrenches. The bolts operate effectively across industrial temperature ranges (-50°C to +150°C) and withstand significant axial loads. While offering excellent shear resistance and compatibility with DIN/ISO components, they require precise torque calibration and proper washer integration to prevent material deformation in heavy machinery applications.
