Grade 5 Carriage Bolts in Bulk

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 Specifications of Grade 5 Carriage Bolts

Grade 5 Carriage Bolts are manufactured from medium carbon steel (0.25% to 0.60% carbon) and have a minimum tensile strength of 120,000 PSI.  They are preferred in applications demanding a higher strength bolt with long lasting dependability and durability.  They are readily available in plain finish, and electro-zinc.
