About This Part
This shaft transfers rotary control through a sealed front cover, and titanium earns its place there: Ti6Al4V brings high strength at low density with excellent corrosion resistance, so the shaft keeps turning in environments that would pit a plain steel part. The blank is Grade 5 bar in the annealed condition, per GSA 08 3040 material callouts.
The route is pure turning discipline. The bar is turned to all rotary dimensions with chamfers and flash removed, leaving an extended tip for a center; a second pass removes the tip and sets final total length; a bench pass deburrs and dresses the edges. The double hex profile drives the mating element without slip, and the general surface runs at Ra 3.2 um.
Every thread is gauged with go and no-go ring or plug gauges, every fit hole checked with a plug gauge, and the finished parts are passivated for surface stability. A 3.1 material certificate accompanies each shipment, and drawing dimensions are inspected 100 percent.

Common Questions
Why titanium for a control shaft?
Ti6Al4V keeps high strength at roughly half the weight of steel and shrugs off corrosion that would pit plain or plated steels. On a shaft that passes through a sealed cover and must keep moving cleanly, that combination justifies the premium.
Is the annealed condition important?
Yes, annealed Grade 5 machines more predictably and delivers stable, well distributed mechanical properties; the material callouts on this part specified it and we certified it.
What does the 3.1 certificate cover?
It certifies the actual melt chemistry and mechanical properties of the bar stock used for your shipment, issued by the material producer and passed through with the parts.
