I should've said applying lube before drilling. I would suggest drilling a smaller hole in the screw remnant and with the aid of a special bit that has a tapered thread running in the opposite direction of the screw's thread. Now, when you insert this special bit and turn it anti clockwise, it will start to grip into the screw part during the turning effort.101Volts wrote:And I don't think any type of lubricant will help getting it out without drilling.
