What do you use to heat up a screw held in place by blue lock-tite si I don't destroy my optic? Some sort of heat gun, but what?

I've never had a loctited screw not unloosen when applied with normal deliberate force with screwdriver

Blue loctite should not require heat in order to loosen. It is the red that requires heat.

can't remember what I used, but if I put any more pressure on these screws they will strip. Might have used red. I'm going to have to get a heat gun from Grainger I guess. I lock-tite the crap out of stuff because I;ve had stuff come loose at the wrong time. I just have hell getting them back off.

There is no problem with using loctite, just make sure you use the right loctite for the correct application. With very small screws, using red is usually not a good thing. Think of it this way, blue is for "temporary" whereas red is usually "permanant".

With scopes I use blue on the base screws. I have seen red used, but that requires adding heat and you really do not want to do this. Blue will work just fine.

There are MANY types of loctite. Wicking, thread locker, blue, red, etc., etc.

Blue: Can be removed with hand tools
Red: Apply heat to remove
Green: Apply heat to remove


Google 3 seconds

dont go buy a heat gun if you already have a soldering iron. Just lay the tip on the screw for a minute or so(depends on the watts of the iron and the size of the screw how long you leave it in the screw).

Can using "blue" over and over in the same spot cause any issues after a while?

Thank-you for the reply. However, I think this only refers to red. The other threads say that red needs heat where as blue needs a strong twist.

i know for a fact the red tube with blue liquid does not need heat, easy as pie to unscrew

Hold a soldering iron to the head of the screw. It will heat the screw and not your optic. I'd be carefull using a heat gun.
