Description
1/4" X 2 1/2" X 18" Starrett Oversize Precision Ground Flat Stock | AISI A-2 Air Hardened Steel | 57173 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 flat stock provides a consistent, true surface across the length for accurate machining and squaring fixtures.
- AISI A-2 air hardened tool steel offers solid edge retention and dimensional stability under typical tooling and forming operations.
- Oversize length accommodates final shaping, planing, or milling to exact dimensions without sacrificing rigidity.
- Uniform cross section (0.25 inch thick, 2 1/2 inch wide) supports predictable machinability and tooling behavior.
- Single piece construction minimizes joints or weld-related distortions during fixturing or grinding tasks.
