Stainless Steel Coach Bolts

Stainless Steel Coach Bolts  AS 1390 is a carriage bolt of a specific standard. The head of the Stainless Steel Coach Bolts  AS 1390 is round, similar to a mushroom head or a domed head. This round head does not have a cross slot or hexagon socket that can be used for power tools, and the 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 carriage bolt is often used to connect building structures, such as bridge railings, building curtain walls, steel structure frames, etc. Jinan Star can produce carriage bolts with higher strength, which can withstand greater tension and shear force to ensure the reliability of the connection. Different grades of carriage bolts (such as 4.8, 8.8, etc.) will vary in strength and can be selected according to specific usage scenarios and requirements.
