The carriage bolt is applied in the groove. The square neck is stuck in the groove during the installation process, which can prevent the bolt from turning. The carriage bolt can move parallel in the groove. Because the head of the carriage bolt is round, there is no design of the cross groove or the inner hexagon, which can also play an anti-theft role in the actual connection process.
