The distinguishing characteristic of a carriage bolt lies in its domed, mushroom-shaped head, complemented by a square neck beneath it. This square neck is designed to prevent the bolt from rotating during installation, ensuring a secure and tight fit.
The head of the carriage bolt is typically smooth and round, providing an aesthetically pleasing finish. Furthermore, these bolts are available in a range of materials, with galvanized and stainless steel options being popular choices for their corrosion resistance.
What are they used for
The carriage bolt, which is a fastener, is typically used in woodworking, construction, and other heavy-duty applications.
They are used for creating wood frames and wood beams and most wood to sheet metal fastening because its unique shape makes this the best contender when it comes to holding wood together. The square shoulder ensures that the structure being built is rigid, by restricting the movement of the materials being joined.
