5/16″ X 4″ X 36″ Starrett Oversize Precision Ground Flat Stock | AISI A-2 Air Hardened Steel | 56917 is Starrett precision ground flat stock, supplied ground flat, square and parallel in aisi a-2 air hardened steel so it goes straight into layout, fixturing and machining work without further surfacing.

Precision ground surface provides flatness suitable for milling, drilling, and finishing operations

AISI A-2 air hardened steel delivers wear resistance and edge stability under repeated tool contact

Single-piece construction minimizes misalignment during fixturing and setup

Good dimensional stability across the length helps maintain consistent tolerances in fixtures

Versatile for die making, tooling, forming, and fixture fabrication
