Express Delivery 3/16″ X 1/4″ X 18″ Starrett Precision Ground Flat Stock AISI O-1 Oil Hardened Steel 57230

3/16″ X 1/4″ X 18″ Starrett Precision Ground Flat Stock | AISI O-1 Oil Hardened Steel | 57230 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 surfaces provide repeatable alignment for fixtures and jigs.

AISI O-1 oil-hardened tool steel offers robust wear characteristics for tooling and prototyping.

Compact flat stock dimensions support small fixtures, reference surfaces, and custom tooling components.

Consistent stock dimensions across the length of the piece reduce setup time in machining workflows.

Ideal for creating fixtures, shims, reference blocks, and custom tooling where precise flatness matters.
