The go-to fastener for wood-to-wood and wood-to-metal connections, metric carriage bolts DIN 603 may be fully or only partially threaded. The square neck beneath a shallow mushroom head self-locks the bolt when it is inserted through the square hole in a metal strap. The standard carriage bolt has a round head and a square neck, but they also are available with oval necks, ribbed neck, or no neck. Some come with fins. Other have square heads.
