1/4″ X 3 1/2″ X 18″ Starrett Precision Ground Flat Stock AISI O-1 Oil Hardened Steel 54079 Next Day Delivery

1/4″ X 3 1/2″ X 18″ Starrett Precision Ground Flat Stock | AISI O-1 Oil Hardened Steel | 54079 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.

One piece construction provides a uniform, flat contact surface for alignment and fixture work

Precision ground surfaces ensure squareness and flatness for accurate machining and measurement

AISI O-1 oil hardened steel offers reliable hardness after heat treatment and good wear resistance for tooling applications

Oil hardening reduces distortion during heat treatment compared to water-quench methods, improving dimensional stability

Standard thickness and width enable straightforward clamping, fixturing, and setup in milling, drilling, or grinding operations

Ideal as raw stock for custom tooling, dies, shims, gauge blocks, and fixture components
