Hex Bolt (Half Thread)

Hex bolts (half thread) are externally threaded fasteners with a hexagonal head and partial threading along the shank. Designed for high-strength fastening where shear strength and precise alignment are critical, they are widely used in construction, machinery, and automotive applications. The unthreaded portion provides better load-bearing capacity and reduces the risk of thread stripping under heavy clamping forces.
