Checking stretch can be done with calipers or even by feeling for the screw to be thinner at some point if the screw is long enough to do so. Most screws are not hardened so it is easy to stretch them or for them to have excessive wear. If you feel that either or both conditions exist replace them. With good screws .

The Red thread locker is too strong and will make disassembly nearly impossible
