DIN603 carriage bolts are characterized by their domed or mushroom-shaped heads and square necks beneath the head. These bolts are designed to be inserted into pre-drilled holes and tightened from the opposite side, preventing the bolt from turning during installation. Carriage bolts are commonly used in wood-to-wood and wood-to-metal applications, providing a secure and visually appealing fastening solution. The square neck of the carriage bolt prevents it from turning when the nut is tightened, making it suitable for applications where a smooth and finished appearance is desired.
On the other hand, washers are used in conjunction with hex nuts to distribute the load of the fastener evenly and prevent damage to the surface being fastened. Washers also help to reduce friction between the nut and the surface, making it easier to tighten the fastener. There are different types of washers available, including flat washers, lock washers, and spring washers, each serving a specific purpose in fastening applications.
