High-Performance Carriage Bolts for Demanding Applications
THREAD INDUSTRIAL CO., LTD. specializes in the production of DIN 603 standard Carriage Bolts, also known as coach bolts. These fasteners are distinguished by their domed or countersunk head and a square neck underneath, which self-locks into wood or metal to prevent the bolt from turning when the nut is tightened. This design makes them ideal for securing wood-to-wood or wood-to-metal connections in construction, woodworking, and industrial assembly.
