Adaptable box screws seized

[KWCFC]

Hi fellas

I've got a site where I need to get into these adaptable boxes but every screw is stuck and just gets mashed up when I turn the screwdriver.

Any clever tricks to know about before I have to break the lids off? ?

With these boxes the lid seals often swell also if it is warm the air trapped inside expands so if you push on the lid and waggle the screw as you try to undo it they will normally come loose

God I hate those plastic screws

Nice one buddy! It worked for 2 out of the 4 screws but it gave me enough space to do what I needed.

Glad it worked for you
I always put a bit of silicone grease on the screw threads so it makes them easier to undo
