OEM manufacturer Din571 Din571 - Carriage Bolt – Sunshow Detail:
The carriage bolt is applied in the groove, the square neck is stuck in the groove during the installation, which can prevent the bolt from rotating, and the carriage bolt can move in parallel in the groove. Because the head of the carriage bolt is round, there is no cross groove or inner hexagon tool design available to help prevent theft in the actual connection process
