Rounded, Domed Head: The smooth, shallow dome of the carriage bolt’s head provides a clean, flush finish, making it suitable for visible applications where aesthetics are important, such as in furniture construction or decking.
Square Neck for Anti-Rotation: Beneath the head, the square neck prevents the bolt from turning during installation. This feature is particularly useful when the bolt is inserted into a square hole in metal or when used in wood, as it ensures a secure connection without the need for a second tool.
Threaded Shaft for Secure Fastening: The shaft of the carriage bolt is threaded, allowing for a nut to be securely fastened on the opposite side. This threading ensures a tight and durable connection between materials.
