Need to take out Double Glazed window.

[boydycx]

Just brought a new bed and can't get it up the stairs, thought I'd take out the window as it would fit but i can't release the screws.
I have even tried to use a drill and screw bit but they will not budge. Any help appreciated.
Thanks in advance.

If you haven't already stripped the screwhead then take a centre punch and put it in the centre of the screw and strike it firmly but not too hard with a hammer. This will sometimes be enough to unstick the screw and you can then undo it normally. Failing that you can purchase a Screw Extractor set which should remove them. http://www.screwfix.com/app/sfd/sea...extractor&n=&pn=1&pd=1&pi=1&cn=1&cd=1&x=0&y=0

You could try an 'impact' socket wrench fitted with either a flat or cross headed blade available from motorist shops (halfords)
Or you could try placing the screwdriver in position and striking it with a hammer a few times to loosen the screws.
If all these fail you may have to use a pad saw fitted with a hacksaw blade and get in behind the frame and saw through the screws.
Screw extractors require a drilled hole to engage the extractor and the hole required is probablely larger than the screw and if you can't drill the hole then you have failed before you start.

Does anyone know how this works ? Is it pilot hole then screw it to break it?

Yes! you drill a hole 3mm to 4mm is about the smallest size and insert the screw extracor like you would for tapping a thread but anti clockwise and using a tap wrench you turn the extractor which is tapered so as you turn it bites in, and out comes the screw.
Thats the theory, in practice it don't always work if the screw is really tight or the hole is not deep enough. Also if the remaining wall thickness after drilling is thin, then it just breaks up leaving you back to square one.
I would say not suitable for wood screws but ok for machine screws from about 6mm upwards.(that is after soaking with penitrating oil)

Thanks for the info mates. The screws are still in tact but will purchase from screwfix as they are well cheap.
Thanks Steve.

Hi Steve,
Will you let us know how it works out, because I feel you will have little success with the screw extractor, Have you tried drilling holes in screws?
Not easy! I can assure you.
