Yes. This Warne Savage AXIS & Edge XP Tactical Rail will fit your Savage Axis and includes tapered 6-48 screws for proper installation.
The Warne Savage AXIS & Edge XP Tactical Rail only fits the Axis, Axis ll, Edge w/6-48 screws. I do not believe it will fit your A22. I would recommend reaching out to the manufacturer to confirm.
If you have a Savage Axis or Savage Edge in a short action, then yes these rails will work for your rifle.
