A "kingbolt" refers to a vital component in the structure of a horse-drawn vehicle, particularly wagons or carriages. It is a strong vertical rod or bolt that extends from the front axle upward, passing through the wagon's main body or forecarriage. The purpose of a kingbolt is to provide stability and support, effectively connecting the front axle to the vehicle's body, thereby ensuring its structural integrity.
Typically made of durable metal, such as iron or steel, the kingbolt protrudes at the top, allowing it to attach to a pivotal mechanism called a kingpin or king post, forming a pivotal joint. This connection permits the forecarriage to swivel horizontally, relative to the wagon's body, allowing for smooth turns and maneuverability.
The term "kingbolt" is derived from the word "king," which generally denotes authority or significance, and "bolt," referring to a durable fastener. This name highlights the crucial role the kingbolt plays in providing strength and stability to the horse-drawn vehicle's overall structure.
In summary, a kingbolt is a vertical rod or bolt that connects the front axle of a horse-drawn vehicle to its body, ensuring stability and supporting the pivotal mechanism necessary for smooth turns. It is a key component in the construction of such vehicles, emphasizing its importance in maintaining their structural integrity.
The word "kingbolt" has an interesting etymology that can be traced back to Old English and Old Norse languages.
The term "kingbolt" derives from the Middle English word "kyngbolte" which was a compound of "kyng" meaning "king" and "bolte" meaning "bolt" or "beam".

The reason behind the association with the word "king" is a bit uncertain, but it is believed to be due to the fact that the kingbolt is a crucial component in a structure or mechanism, much like a king is seen as the central figure of power and importance.
Overall, the etymology of "kingbolt" reflects its role as a significant and pivotal element in various mechanical constructions.
