Product Description
Segment Bolt Nut is a type of threaded fastener. Nuts are almost always used in combination with matching bolts to hold multiple parts together. Through the friction of the thread (slight elastic deformation), the slight tension of the bolt and the compression of the parts to be fixed, the two parts are held together. Segment Bolt Nut is widely used to fasten and connect two parts with through holes.
