Description
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
