Our Half Thread Hex Bolts (Partially Threaded) are engineered for critical structural joints where shear strength is paramount. Featuring an unthreaded shank (grip length) below the head, these bolts provide stronger alignment and load-bearing capacity than fully threaded alternatives. They are the industry standard for steel construction, heavy machinery, and automotive applications where the bolt body must withstand high lateral forces.
