Limited Time 5/16″ X 3/4″ X 18″ Starrett Precision Ground Flat Stock AISI O-1 Oil Hardened Steel 54103

5/16″ X 3/4″ X 18″ Starrett Precision Ground Flat Stock | AISI O-1 Oil Hardened Steel | 54103 is Starrett precision ground flat stock, supplied ground flat, square and parallel in aisi o-1 oil hardened steel so it goes straight into layout, fixturing and machining work without further surfacing.

Precision ground flat stock provides consistent flatness for milling, drilling, and grinding setups

AISI O-1 oil hardened steel offers good machinability with solid wear resistance for tool and die work

One piece construction minimizes joints, improving rigidity during fabrication and forming

Ideal for custom tooling, jigs, fixtures, and homemade dies where precise dimensions are required

Prepares well for further shaping, such as milling, grinding, or heat treatment as part of project workflows
