Description
3/8" X 2 1/2" X 18" Starrett Oversize Precision Ground Flat Stock | AISI D-2 Air Hardened Steel | 69428 is Starrett precision ground flat stock, supplied ground flat, square and parallel in aisi d-2 air hardened steel so it goes straight into layout, fixturing and machining work without further surfacing.
- Oversize blank provides material for final dimensioning, squaring, and custom edge preparation without risking undersize stock.
- Precision ground surface delivers flatness and straightness suitable for fixture bases, tooling jigs, and die work.
- AISI D-2 air hardened steel offers good wear resistance and dimensional stability after heat treatment or surface grinding.
- Rigid rectangular profile minimizes deflection during light to moderate machining and filing operations.
