The bolt (or whatever is left of the screw) is pertruding? If so can use plier to turn it out....

If the bolt is embedded in the thread hole... best way is to prob drill it out... Will risk spoiling the threads but since it is alu, u can easily tap the thread for screws 1 size bigger...

Good luck! Sticky prob u have there...

I have tried drilling.Perhaps the screw is hard.It is embedded flush with the aluminium part.someone suggest to me to use a dremel to create a slot and turn using a screwdriver.But i thnk its too small..and i do not have a dremel.

can the screw be repositioned? As in, can u scrap the current screw hole and jus thread another somewhere else?

You can also drill a hole just beside the existing one so u get the slot to pry the broken screw out...

No dremel, can use a grinder bit afix to a regular bench drill / hand drill... just that this setup is clumsy...can grind ur way through. Screws are usually harden steel...regular high speed steel drill bits at high rpms should eventually wear down the screw if u persevere

Maybe u could post a photo of the situation. Others here might be able to help

How Small

yes, how small is the screw? if too small like say 1.5mm is very hard to get it out.

I suggest u drill a small hole in the centre of the screw.

Then get the screw extractor tool and fit it into the newly drilled hole.

With the use of WD40 n screw extractor, unscrew the broken screw out in the normal anti-clockwise direction.



Tis type of situation occurs usually in my previous coz of work.

There is a method that I previously use . Try to saw/dremel the screw to create a "-" mark. make sure it is deep and narrow. Then use screw driver (flat screw driver) to try to screw it out.

If its a through hole at the other end, juz use a small size drill bit to drill thru. As the momenteum of the drill bit will follow the screw thread n it will screw the broken screw out at the other end.

this thread's name is so...

another way is use a small flat or philip screwdrive and a hammer, slowly hammer the screwdriver on the side of the broken bot in the direction of unscrewing.. ANTI-CLOCKWISE. slowly until you see the bot start to move and lossen itself.. try it.. it work for me when I in the army time, during field recoverary for vehical.

haha shark, your method works for big bolts. I use that too when in the army. but i think the size of his screw is too small for it.

Thanks all

Thanks all for the suggestion.sManaged to removed all 3 screw shaft using Superhornet method.I got a dremel to cut a narrow line across the screw diameter.It cut across the metal part too,but it does not affect the function.Thanks.!

Congratulation!! Glad that the method works.
