A307 Grade A Carriage Bolts

Round head square neck bolts are referred to as Carriage Bolts. With their trademark shallow, mushroom-shaped head, these bolts are intended to be used in low profile applications where access to installing and removing the bolt is only available from the nut side. This includes many wood-to-wood or metal-to-wood applications. Because of the 1-sided access, they are also often used in applications where tamperproof access is desired.

Manufacturing of A307 Grade A Carriage Bolts

A307 Grade A Carriage Bolts are manufactured from low carbon steel (less than 0.25% carbon) with a minimum tensile strength of 60,000 PSI, making them ideal for a wide range of general purpose applications. They may be supplied in a standard neck, short neck, ribbed neck, or fin neck. They are readily available in plain finish, electro-zinc, and hot-dip galvanized.
