Starrett 55066 Low Carbon Steel Flat Stock 24x1.5x1.5 in

Product Description

The STARRETT 55066 is a low carbon steel flat stock bar measuring 24 inches long by 1.5 inches wide by 1.5 inches thick, conforming to AISI Type C1018 material specification. This is a cold-finished, precision-tolerance steel bar used in fabrication, toolmaking, fixturing, and general metalworking applications. The C1018 alloy offers good machinability and weldability, making it a practical choice for structural components, brackets, and custom parts requiring close dimensional control. Weight is approximately 15.3 pounds per piece. Tolerances are held tightly across all dimensions, making this stock suitable for precision layout and machining work.

This flat stock is used across general manufacturing, maintenance and repair operations, machine shops, and fabrication facilities. It is suited for projects where square, close-tolerance bar stock is required without additional machining of the raw material faces. Typical applications include jig and fixture bases, slide ways, spacers, and structural weldments. The 24-inch length accommodates a wide range of cut-to-size applications in both light industrial and trade settings.

Compatibility

Designed as a general-purpose AISI C1018 low carbon steel flat bar suitable for fabrication, toolmaking, fixturing, and maintenance repair operations requiring precision-tolerance square bar stock.

Installation Notes

Cutting, drilling, and welding of C1018 steel flat stock should be performed by qualified metalworkers or machinists using appropriate personal protective equipment and ventilation. Secure the bar firmly in a vise or fixture before machining to prevent movement. Deburr all cut edges before handling or assembly. Follow applicable shop safety standards and local codes when welding or cutting.
