coach bolt, has a domed or countersunk head,
and the shank is topped by a short square section under the head.
The square section grips into the part being fixed (typically
wood), preventing the bolt from turning when
Carriage bolts used in the slot, the square neck in the process of
installation card stuck in the slot, can prevent the bolt rotation,
carriage bolts can be parallel movement in the tank. Because the
head of the carriage bolt is round, there is no design of the

also act as an anti-theft function in the actual connection
process.
