1018 Cold Rolled Hexagon Bar is produced through cold drawing, a process that improves its strength, tolerance, and surface finish over hot rolled steel. Compliant with ASTM A108, this low-carbon steel provides a balance of toughness, strength, and ductility. Its key characteristics include excellent machinability and good weldability, making it a versatile choice for general fabrication and manufacturing.

As a small-sized hex bar, this 5/16" dimension is perfectly suited for producing custom fastener stock, small fittings, precision hardware, and standoffs. The hexagonal shape provides a secure gripping surface for tools, making it a primary choice for nuts, bolts, and valve components.
