Starrett 55043 Low Carbon Steel Flat Stock 24x1.5x1 in

Product Description

The STARRETT 55043 is a low carbon steel flat stock bar measuring 24 inches long, 1.5 inches wide, and 1 inch thick, conforming to AISI Type C1018 material specification. This bar stock is precision-ground to tight dimensional tolerances, making it suitable for machining, fabrication, tooling, and general metalworking applications. At 10.2 pounds, it offers substantial mass in a standard flat bar profile. Thickness and squareness are held to plus or minus 0.001 inch, while width tolerance runs plus 0.000 to 0.005 inch, and length tolerance allows up to plus 0.625 inch. Machinists, tool-and-die makers, and fabricators rely on this stock for fixtures, brackets, wear plates, and custom components.

C1018 low carbon steel is one of the most widely used grades in general machining and fabrication shops. Its low carbon content makes it highly machinable, weldable, and suitable for case hardening. This flat bar is appropriate for both light manufacturing and maintenance repair operations in industrial, commercial, and trade settings. It is commonly used for structural supports, jigs, fixtures, and custom fabricated parts where tight dimensional control is required from the raw stock.

Compatibility

Designed as a standard AISI C1018 low carbon steel flat bar for general machining, fabrication, and tooling applications across industrial and trade environments.

Installation Notes

Cutting, drilling, or machining should be performed by qualified machinists or fabricators using appropriate metal-cutting tooling and personal protective equipment. Secure the workpiece firmly before any cutting or grinding operation. Edges and cut surfaces may be sharp — deburr before handling or assembly. Follow applicable workplace safety standards when working with raw steel stock.
