Half Thread Hexagon Bolts
Half Thread Hexagon Bolts feature an unthreaded section, enhancing their strength compared to fully threaded hex bolts. The unthreaded part serves various purposes, such as reducing vibration, functioning as a dowel, or allowing a component to rotate around it. Secure the component in place using a hex nut.
