A crown bolt is a high-quality fastener that gets its name from its shape that resembles a crown.

Crown bolts have high preload and fatigue resistance to provide reliable connection fixation. Its nut part adopts a special anti-loosening design, which effectively prevents loosening and falling off, and ensures a safe and reliable fastening effect.
