Hello,

I bought a motherboard off of E-bay which is otherwise fine but there is a screw broke off in the parallel port. :/ I'd very much like to remove it but I'm not sure how I go about it?

Thanks.

yeah you could try a jewellery store, finding an extractor that small might prove difficult though you could try Amazon and extractors are pretty cheap.
You would need to drill a small hole first,say 1mm then enlarge it in 0.5mm increments until you had a hole big enough to screw in the extractor which will screw in counter clockwise by the way.
A normal home drill would work but you will need a steady hand not to break the small drills.
By the way the parallel plug would still hold in pretty well with only one retaining screw a lot of people never used the screws anyway.

Hi
very few people use parallel ports nowadays however if you do use it and you must secure the plug on both sides then the only sure way would be to drill a hole in the centre of the broken off screw and use a screw or stud extractor to remove it.
If it is not overtight you could cut the shaft of a screwdriver to give you a flat end then superglue this to the broken screw.and turn it out.

Well I bought this PC for legacy uses so securing parallel port devices is important to me.

Any idea what size drill bit I'd need to drill a hole in the screw? Could I do it with a standard home drill? And then what size extractor?

Is this something a jewellery store might be able to help me with? Buying an expensive extractor set may be impractical for me.
