Carriage Bolt is a common mechanical fastening element which is widely used in various construction applications to make joints in between various types of metallic and nonmetallic components with a high clamping force. It is provided with an oval head and the shank is machined with highly precise and dimensionally accurate threads over the 3/4th of its length.
