Standard for keys and keyways/keyseats design (Aircraft)

[Helepolis]

Hi all,

Is there an accepted standard (e.g. MIL, MS etc.) for designing keys and keyways/keyseats for aircraft components?
I need for designing a rectangular key with one end rounded.
Not sure if its relevant but the key material has to be stainless steel.

Google and various LLM's didn't help too much, the closest answer I got was that there isn't any particular standard for keys and ASME B17.1 is acceptable.
So I want to double check.

I'll assume you've done the research, tho' I do think it odd that there isn't a MIL STD keyway.

If the ASTM defines a geometry, then great, but someone will have to stress it for your application.
Presumably you size a key to transmit an amount of torque ?

The MIL specification was:

MS35756
KEY, WOODRUFF, STEEL ALLOY, WITH KEYWAY AND KEY SLOT DIMENSIONS (S/S BY NASM35756)
