ASME B18.5-2 Round Head Square Neck Bolts

Round head square neck bolts in ASME B18.5-2 are generally considered a type of carriage bolt. Carriage bolts, also known as round head square neck screws, are a type of bolt with a round head and square neck. Regarding the round head square neck bolt, its head is round and the neck is square. This design can provide a larger contact area and increase the friction between the bolt and the connecting piece, thereby providing a better tightening effect. In addition, the square neck section prevents the bolt from slipping or turning when rotated, further ensuring the stability of the connection. Carriage bolts (including round head square neck bolts) are widely used in a variety of industries, especially in joints where strength and reliability are required, such as vehicle manufacturing, mechanical engineering and the construction industry. In these applications, carriage bolts can effectively connect two parts with through holes and, by mating with nuts, achieve fastening and retention.
