Okay Howard.
Explain how you would tell these apart if blind?
What does your engineering background, since you reference here, teach you about working via touch alone? That is my situation here. I must be able to safely apply this, without seeing its shade onto an extremely small space. Or, I can take this scanner and this ring to a business and pay someone to replace the ring.
if so, where?

Karen,

  I am a mechanical designer and drafter.  I am an engineering technologist, 
certified by OACETT (http://oacett.org).

  Ask about threadlockers in the hardware store.  The really popular one is 
Loctite 242, which is a lubricating, medium strength threadlocker which is blue 
in colour.  This is very nice stuff for mechanical assembly.  The lubrication 
gives you better control over tightening torque, which is really cool if you 
are using a torque wrench. :)  Alternate threadlockers can be sealing or 
wicking.  Wicking might be very nice for you, but you probably won't find this 
stuff in a regular store.  Most threadlockers are based on Military Standard 
MIL-S-46163A, and several manufacturers make equivalent, compliant stuff.  The 
colours are part of the standard.  Purple is low strength, blue is medium, and 
red is high strength.  The blue, medium strength is good.  The red, high 
strength is difficult to remove without damaging things.

  The regular Loctite threadlockers can be very nasty around plastic 
electronics like connectors and PCB components.  Be very, very careful to apply 
it only to metal components.  I have had some nasty experiences with this.

  Consider usng Krazy glue, and wicking it into the thread.  If you don't glue 
your fingers together, you should be fine. Look for a thin cyanoacrylate glue.  
The thick, goopy stuff won't wick.

i  feel better that i can place some of the locktite on the ring, then put
it into position.
Will seek it at walmart or Home depot.

 I have the ring.
 I even have more than one.
 so you put this liquid on the ring and it sticks in place?
 Where do I get this product?

Typically hardware stores, etc..  Walmart has it.
