Thread-lock: Locktite. So, THAT"S what that stuff is. I might just have some.
Be a little careful that what you are intending to use is actually “Thread-Locking” material.
Loctite is just a brand name, most of their products are high performance adhesives, use one of those and the only way to remove your drive will be to drill the screws out or heat the drive to over 100 deg C to break down the adhesive – NOT RECOMMENDED!.
Also Thread-lock is available in different types, depending on whether the part will ever be disassembled, make sure you choose the one that allows this. Then use the thread locking compound VERY SPARINGLY and all will be well.
As for torquing up the screws, if you use those small handy “jewellers” screwdrivers then (theoretically) it will be difficult to over do it because you just can’t exert the same force with those puny screwdrivers as a standard one.
And….. finally, if you do use thread-lock, you hardly need to apply any torque at all, just stop when you meet the first resistance, the thread-lock will do the rest.
