Impact screws up screw head!

[feelergaugephil]

Ok, so that stubborn screw wont come out! So you use the impact driver to get them out and it mess's up the head!!
Simple tip....... Use an extension 3/4 on the impact head, dont use the impact just yet, use a hammer and knock the extension (with bit on the end) and drive in into the screw, this will make the rounded off screw get a forced groove in it, once it resembles a screw head again, now you can go ahead and use the impact

Then buy some allen head screws.

Best to just drill them out and extract them out all right from the start. Then replace with allen or hex screws. This saves you all the trouble of stripping them, cursing them, hammering them and then drilling and extracting. [/img]
