3/4″ X 5″ X 36″ Starrett Oversize Precision Ground Flat Stock AISI A-2 Air Hardened Steel 57442 Certified

3/4″ X 5″ X 36″ Starrett Oversize Precision Ground Flat Stock | AISI A-2 Air Hardened Steel | 57442 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 surfaces provide reliable flatness and squareness for machined fixtures and tooling

AISI A-2 air hardened steel offers toughness and wear resistance while maintaining dimensional stability after final machining

Oversize stock enables material removal to final dimensions with reduced risk of edge waviness or nonconformance

Solid rectangular form supports stiffness in jigs, bases, and fixture components during milling, drilling, and grinding

Suitable as raw material for custom gauges, dies, pattern plates, and bespoke tooling structures
