Starrett 57250 Steel Flat Stock 24x5/16x5/16 in C1018

Product Description

The STARRETT 57250 is a low carbon steel flat stock bar measuring 24 inches long by 5/16 inch wide by 5/16 inch thick, manufactured to AISI Type C1018 material specification. This solid steel bar is used for fabrication, machining, repair work, and custom part creation across a range of trade and industrial applications. The stock is held to tight dimensional tolerances — plus or minus 0.001 inch on thickness and square, and a width tolerance of plus 0.000 to 0.005 inch — making it well suited for precision fit-up and layout work. Machinists, millwrights, pipefitters, and general fabricators commonly work with C1018 flat stock for brackets, spacers, keystock, and structural repair components.

This flat stock is appropriate for light to medium fabrication tasks in residential, commercial, and industrial settings. Its low carbon content makes it easy to cut, drill, weld, and machine with standard shop tooling. The 24-inch length provides a workable starting blank for a variety of cut-to-size applications. It is sold as a single piece and is suited for jobs where a precise, machinable mild steel bar is required.

Installation Notes

Cutting, drilling, or welding this stock should be performed by a qualified machinist or fabricator using appropriate personal protective equipment and shop safety procedures. Secure the workpiece properly before cutting or machining to prevent movement and dimensional error. Deburr all cut edges before fitting or assembly to avoid injury and to ensure accurate mating surfaces.
