Common Dimensions of Heavy Hex Nuts
In addition to considering the material and size of the carriage bolts, it is also important to choose the right type of nut to secure the bolt in place. A hex nut is a common choice for carriage bolts, as it provides a secure fit and is easy to tighten with a wrench. Nylon lock nuts are another popular option, as they provide added security by preventing the nut from coming loose due to vibrations or movement.
