Product Description

This M12x190 half-threaded hex bolt features an external hexagonal head design with a partial threading configuration, optimized for applications requiring both gripping strength and adjustable fastening. Constructed from grade 8.8 carbon steel with zinc plating, the M12*190 hex bolt half thread offers a tensile strength of 800 MPa and operates reliably within -50°C to +120°C. Its 190mm shank length includes a 90mm threaded section and 100mm smooth shank, enabling precise alignment in structural assemblies. The external hex bolt M12 190 half thread is IP67-rated for dust/water resistance and compatible with standard M12 nuts across automotive, machinery, and renewable energy sectors. Its half-threaded hex bolt M12x190 design minimizes cross-threading risks while allowing rapid installation with 19mm wrench flats. Limitations include reduced shear resistance in non-threaded sections compared to fully threaded alternatives. Surface hardness reaches 32 HRC, supporting torque values up to 118 Nm.
