Starrett 54953 Steel Flat Stock 24x1-1/4x5/16 in C1018

Product Description

The STARRETT 54953 is a low carbon steel flat bar stock machined to close tolerances and suited for precision layout, fabrication, and toolmaking applications. Conforming to AISI Type C1018 material specification, this flat stock measures 24 inches in length, 1-1/4 inches in width, and 5/16 inches in thickness, with a finished weight of 2.66 pounds. Thickness and square tolerances are held to plus or minus 0.001 inches, width tolerance is plus 0.000 to 0.005 inches, and length tolerance is plus 0.625 inches. These tight tolerances make it appropriate for applications where dimensional consistency is critical.

This flat stock is used in metalworking shops, maintenance facilities, and light manufacturing environments. Typical applications include tool and die work, fixture building, machine part fabrication, and general repair or fabrication tasks where a reliable, weldable low carbon steel bar is required. Its C1018 designation indicates good machinability and weldability, making it a common choice for parts that require drilling, tapping, or welding without extensive pre-treatment.
