DIN603 Carriage Bolts Application Scopes
DIN603 carriage bolt is generally used for marble installation of dry pendant. When tightening, the bolt rod will not turn because of the role of square neck, which is easy to fix and install. It is mainly used in some places where counter head screws are needed.
Because of the round head of the coach bolt, there is no design of available assistance tools such as cross grooves or inner hexagons, which can also play an anti-theft role in the actual connection process.
Carriage bolt is widely used in automobiles, new energy electric vehicles, and bridge engineering, which can play a good role in fastening clamp.
