Default Is Loctite a must for scope mounting?

I know many regard using blue Loctite (blue or whatever color refers to the less than permanent version) when mounting a scope as a mandatory part of proper scope mounting.

However, I never do it. I often find I want to fine tune my scope mount down the road, adjusting the eye relief or leveling. So I don't use the Loctite.

Anybody else skip the Loctite? Is it really necessary if the screws are properly torqued?

I've found it depends on the quality of the rings.
Cheaper versions tend to loosen. I always use blue LocTite on mounts and rings. Better safe than sorry at the range or while in the middle of nowhere hunting.

When a screw goes into a threaded hole, they are held together by several contact points(s), not the entire threaded surface even if they're properly torqued. Vibration force will cause these contact points to separate momentarily; and if enough of these happen at the same time, the screw will back itself out over time. The purpose of Loctite is to fill up the void and create much larger contact surface between the two to maintain its 'grip'. Also, if it's a steel screw going into an aluminum threaded hole, overtorquing can easily strip the thread; in this case always use loctite (non-permanet version if later removal is needed) instead of overtorquing.

Always use blue loctite on threads and NEVER over torque. You would be surprised how easily threaded items come loose with time. The scope base on my FN seemed loose the other day even though the gun was tracking perfectly. A slightly loose set of rear base screws was the culprit. After using loc tite and tightening the screws to 15 inch-pound, my mount base is rock solid again.

Use quality rings. I do not use locktite and torque to 15-20 in/lbs. I have never had a screw back out.

I dry fit...If it seems to move after "tightening" the scope rings then I use loctite.
