Uses of carriage bolts
To better understand what carriage bolts are used for, knowing how they’re constructed is important. By keeping their construction in mind, you’ll make it easier for yourself to understand the purpose (s) carriage bolts serve. A straight cylinder with a flat edge, the carriage bolt has a top with small square neck which resists turning when it’s fastened into place. This means that a carriage bolt won’t perform as it’s supposed to until you countersink it.

Furthermore, when placed through a round hole in most wood or square hole in a metal strap, carriage bolt becomes self-locking thanks to the part right beneath its head forming into a squared section.
Often used in joints designed to withstand significant wear and tear, carriage bolts can take care of themselves. However, to avoid damage during installation, using the right size spanner or wrench to install or tighten the bolt is important. By doing this, you’ll save yourself from a lot of hassle later on.
