Bolt Round Head Square Neck

Bolt Round Head Square Neck in ASME B18.5-2 is generally considered a type of carriage bolt. Carriage bolts, also called round head square neck screws, are bolts with a round head and a square neck. The Bolt Round Head Square Neck has a round head and a square neck. 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 prevents the bolt from slipping or turning as it is rotated, further ensuring the stability of the connection. Carriage bolts (including round head and square neck bolts) are widely used in various 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 join two parts with through holes and, by mating with nuts, achieve tightness and retention.
