Round Head Square Neck Bolt Carriage Bolt

Cup Head Square Neck Bolts are mainly used in situations where the connected parts are not suitable for hexagon bolts due to structural constraints or where the bolts are required to have smooth exposed parts. Such as the foot of agricultural machinery, wallboard, etc. This bolt can be divided into two types according to the head size: ordinary bolt and large half round bolt. The head of the square neck bolt with large half round head is straight and large, but its thickness is slightly thin. This kind of bolt is mostly used in trucks, barges, iron-wood looms, and other wooden structural parts. Because of the large bearing surface of the head, it is not easy to fall into the wooden connected parts. These two kinds of half-round head square neck bolts are rough bolts. Our Company
