Fresh Stock 5/16″ X 1/2″ X 36″ Starrett Precision Ground Flat Stock AISI A-6 Air Hardened Steel 59012

5/16″ X 1/2″ X 36″ Starrett Precision Ground Flat Stock | AISI A-6 Air Hardened Steel | 59012 is Starrett precision ground flat stock, supplied ground flat, square and parallel in aisi a-6 air hardened steel so it goes straight into layout, fixturing and machining work without further surfacing.

Single piece flat stock designed for precise machined surface contact and repeatable setups.

Made from AISI A-6 air hardened steel for improved wear resistance and stability compared to basic carbon steels.

Precision ground flat surfaces minimize alignment errors during fixture construction and gauging tasks.

Ideal as raw material for fixtures, jigs, shims, and gauge blocks in machine shops and fabrication shops.

Baseline material for custom tooling projects requiring consistent dimensions across runs.
