Stainless Steel Carriage Bolt

The head of the Stainless Steel Carriage Bolt is round, similar to a mushroom head or a semicircular head. This round head does not have a cross slot or hexagon socket that can be used for power tools, and its appearance is relatively round and smooth. There is a square neck under the head of the carriage bolt, which is a typical feature of the carriage bolt. The side length of the square neck is usually a standard size so that it can be stuck in the corresponding slot or hole to prevent the bolt from rotating. The Stainless Steel Carriage Bolt has a certain toughness and is not easy to break when it is impacted or vibrated, and it can adapt to various complex working environments. Depending on the use environment, different surface treatment methods of the carriage bolt can be selected, such as galvanizing, hot galvanizing, etc., to improve the corrosion resistance of the carriage bolt and extend its service life. The carriage bolt is often used to connect building structures, such as bridge railings, building curtain walls, steel structure frames, etc.
