A round hook bolt, also known as a J-bolt or curved hook bolt, is a threaded fastener with a rounded hook on one end and a threaded shank on the other. The curved hook provides a secure hold for hanging or anchoring components, while the threaded end allows for nuts and washers to fasten it in place. Round hook bolts are commonly used in applications requiring suspension, restraint, or support of loads where a traditional straight bolt cannot be used.
