Is the security you seek is to avoid the situation where a screw terminal loosens due to vibration and you think that a spade terminal might then become detached, because of gravity and the mounting orientation or spring force in the wire?
If so, you might consider starting with a ring terminal and cutting a small slot in the ring in a direction that isn't in line with the disconnecting force. For example, if I were to mount a motor controller on a vertical surface with the terminals up and down (up=M+/M-, down=V+/V-) I would cut the down rings at the 5 or 7 o'clock position so that I could slide the ring on knowing that if the V+/V- screw terminal loosened somewhat the wire won't disconnect due to the wire being pulled down.
Just a thought in an attempt to avoid removing the terminal screw while also avoiding the effects of vibration on a terminal screw.
