Can i use this on metal set screws going into a plastic housing??

No, this is for metal-to-metal applications. Loctite 425 is recommended for plastic-to-plastic and plastic-to-metal applications.

Is this product ideal for locking my camera strap screw in place?

Yes, I'm using blue Loctite for a BlackRapid strap in a DSLR tripod screw hole. I've also used it for securing Arca-Swiss tripod plates to camera bodies.

Is this good for Conceal Carry holster screws?

To tell you the truth, I don't have any issues with my Conceal Carry holster screws coming loose. But if I did, Loctite 242 is the first place I would go because the idea of losing all of the screws in my Conceal Carry holster is unconscionable.

Does it interfere when using a torque wench?

I always heat up the hardware with a heat gun. This softens the bonding, reducing strain of removals.

I needed this because the screws on my computer had a nasty habit of getting loose and falling out. So far it has been incredibly useful in many other loose-screw related situation around the house, so I'd totally recommend this.

Hay aplicaciones que requieren, o al menos es muy recomendable, utilizar un fijador de rosca. Para eso está toda la línea de estos productos Loctite que resaltan por su calidad. Este producto lo utilizo al ensamblar piezas en mi moto, y va a ser igual de útil en el carro. Esto es dónde la vibración puede hacer que se afloje algo.

Affordable, and happy it came in a small size as I didn't need a lot. Seems to hold well, easy to use, and with the cap you can seal it right back up and use it for later. Will be buying more. Hope this helps!

Anything with the Loctite brand is going to be of quality. The threadlock works fine on steel and titanium bits and creates a strong bond to the pieces.
