Starrett 54981 Low Carbon Steel Flat Stock 3/8 X 12 X 24 in

Product Description

The STARRETT 54981 is a low carbon steel flat stock bar cut to 24 inches long by 12 inches wide by 3/8 inch thick. Manufactured to AISI Type C1018 specification, this cold-rolled flat stock delivers consistent dimensional accuracy suitable for fabrication, layout work, fixturing, and general metalworking applications. Thickness and squareness are held to plus or minus 0.001 inch, making it a reliable choice when close tolerances matter. Width tolerance runs plus 0.000 to 0.015 inch, and length tolerance is plus 0.625 inch. Machinists, fabricators, and maintenance tradespeople use C1018 flat stock for brackets, plates, spacers, and custom components where weldability and machinability are priorities.

This flat stock is suited for light to medium fabrication tasks in commercial and industrial maintenance environments. It is commonly used in mechanical shops, HVAC equipment fabrication, plumbing support structure work, and electrical panel framing. The 24 x 12 inch footprint allows multiple smaller blanks to be cut from a single piece, reducing material waste on job sites or in shop settings. Its 30-pound weight reflects the solid cross-section, so proper material handling equipment is recommended during staging and cutting operations.

Installation Notes

Cutting, drilling, and welding of C1018 flat stock should be performed by qualified metalworkers or trade professionals using appropriate personal protective equipment. Deburr all cut edges before installation in any assembly. When welding to galvanized or coated steel, follow applicable ventilation and safety codes. Secure the workpiece properly before any machining or cutting operation to prevent movement.
