Starrett 54921 Low Carbon Steel Flat Stock C1018

Product Description

The STARRETT 54921 is a low carbon steel flat stock bar made to AISI Type C1018 specification. It measures 24 inches long, 0.5 inches wide, and 0.1875 inches thick, and weighs 0.64 pounds. C1018 is a general-purpose low carbon steel known for consistent machinability, weldability, and moderate strength. This flat stock is held to tight dimensional tolerances, making it suitable for fabrication, layout work, machining setups, and general trade shop use. Licensed trades including HVAC, plumbing, electrical, and mechanical contractors commonly use flat stock like this for brackets, straps, shims, and custom fabricated components.

This flat bar is appropriate for light fabrication and general shop applications in both residential and commercial settings. The 24-inch length provides a workable piece for cutting to size, drilling, welding, or bending. The tight width and thickness tolerances make it useful where dimensional accuracy matters, such as machined parts, alignment fixtures, or repair fabrication. It is sold individually and packaged as a single piece per unit.
