Broken allen key screw

Postby Chris Young » Sun Feb 03, 2008 2:56 pm

I'm trying to remove a floating shelf from my wall. The body of the shelf is attached to the bracket with a screw which is turned with an Allen Key. Unfortunately the hole has become rounded off so the Allen Key will not turn the screw.

Any suggestions as to how I might remedy this before I resort to brute force to remove the shelf from the bracket!

Simply Build It

You could try
a) aralditing a bolt into the rounded hole.
b) drilling the screw and then use a screw extractor
c) drilling with a left handed drill. The force usually loosens the screw concerned. , try regrinding a rh drill to left hand format.
d) there may be room to cut a slot in the top of the allen screw, then use a normal screwdriver.
e) drill the allen screw to its minor diameter and remove remnants of thread with scriber.
Good luck and let me know how you get on

Thanks for your help - drilling with a left hand drill then a bit of brute force got it off the wall
