Starrett 55010 Low Carbon Steel Flat Stock 24x4x0.625 in

Product Description

The STARRETT 55010 is a low carbon steel flat bar cut to 24 inches long, 4 inches wide, and 0.625 inches thick. It is manufactured to AISI Type C1018 material specification, a widely used low carbon steel grade valued for its consistent machinability and weldability. This flat stock ships as a single piece and is suited for fabrication, tooling, fixturing, and general metalworking applications. Machinists, millwrights, and fabricators rely on this stock for jigs, brackets, bases, and structural components where tight dimensional tolerances and predictable material behavior are required. At 17 pounds, it is a solid, single-piece bar ready for cut-to-size work.

This flat stock is appropriate for general industrial fabrication, machine shop work, and maintenance repair operations in both light manufacturing and heavy-trade settings. The C1018 grade is a standard free-machining bar steel that responds well to drilling, milling, turning, and welding without requiring specialized tooling or preheat procedures in most shop applications. It is commonly stocked in fabrication shops, maintenance departments, and tool rooms where on-hand raw material availability reduces job turnaround time.

Key Features

• AISI Type C1018 low carbon steel for consistent machinability and weldability
• Finished to tight tolerances: thickness and square tolerance of plus or minus 0.001 inches
• Width tolerance held to plus 0.000 to 0.005 inches for predictable fit in precision fixturing
• Length tolerance of plus 0.625 inches allows for facing and squaring to final dimension
• Single-piece flat bar format — no cutting or splitting required at the stock level
• 17-pound piece weight suitable for benchtop or vise work without additional rigging

Compatibility

Designed as a general-purpose low carbon steel flat bar for fabrication, tooling, and structural applications requiring AISI Type C1018 material compliance.

Installation Notes

Handling and cutting of steel flat stock should follow standard shop safety practices including the use of appropriate PPE such as cut-resistant gloves and eye protection. Secure the workpiece firmly in a vise or fixture before machining or cutting operations. Edges may be sharp as received — deburr before handling in assembly or inspection contexts. Verify final dimensions after any facing or squaring cuts, as the length tolerance allows for material removal to reach a precise finished length.
