Starrett 57249 Low Carbon Steel Flat Stock C1018

Product Description

The STARRETT 57249 is a low carbon steel flat stock bar made to AISI Type C1018 material specification. It measures 0.25 inches thick by 0.25 inches wide by 24 inches long and is held to tight tolerances suitable for precision fabrication, toolmaking, and general metalworking applications. C1018 is a free-machining, low carbon steel known for its good weldability, machinability, and consistent surface finish. This flat stock is commonly used by fabricators, machinists, and maintenance trades as raw stock for brackets, shims, spacers, guides, and custom components requiring controlled dimensions.

This flat stock is suited for light fabrication and machine shop use in both residential and commercial maintenance environments. Its small cross-section makes it a practical choice for precision shim work, fixture building, and general repair applications where dimensional accuracy matters. The controlled width and thickness tolerances allow direct use in close-fitting assemblies without additional surface grinding. Machinists, millwrights, and general fabricators are the typical end users.

• Single-piece package with no minimum order beyond one unit

Compatibility

Designed as a general-purpose flat bar raw stock for use in fabrication, maintenance, and machine shop applications requiring AISI C1018 low carbon steel in a 0.25 x 0.25 inch cross-section.

Installation Notes

Cutting, drilling, and welding of C1018 steel flat stock should follow standard metal fabrication practices and applicable shop safety procedures. Wear appropriate PPE including eye protection and gloves when cutting or grinding. Deburr all cut edges before fitting into assemblies to prevent damage to mating surfaces. If welding, ensure proper ventilation per applicable safety codes.
