I am replacing my inop turn signal switch and am at the point of removing the two screws holding the old switch in.  I can't turn the damned screws.  The slot is shallower than a normal screw would be and instead of a "normal" slot these are in the shape of a cross.  It looks as if a special screw driver is needed  to engage the cross-shaped slot.  I hoped that a regular flat blade screwdriver would work but it wont (for me!~)   the slot(s)  very shallow and I can't get them to turn.

 

I could call Kirk Tuesday but I'd like to use the car this weekend.  I'd be thankful if someone would tell me how to turn those damned screws.  (I don't see why a phillips head screw could have been used!!)

 

Thanks for any info.

Jack, I've had luck using a small pair of vise grips to loosen and turn them. If you have enough room a dremel tool or small file to gut a groove in the head to allow you to get enough bite to turn the screw.

What your dealing with is a tamper proof screw which is made to be able to turn clockwise but because the back shoulder of the head is tapered off so as not to allow the screw to be turned counter clockwise.

Good luck.

These screws do exist, unfortunately.  Someone used them to secure a couple of door hinges in my house, and they were a real pain to remove.  I finally had to use a flat screwdriver as a pry bar and a hammer to loosen them, then pry/pull them out.  You cannot remove them with a flat screwdriver, as the screw head only allows them to turn in one direction - that of tightening.

They are not a Phillips head screw, nor are they any other type of standard screw.  They are a security screw.

Jack - is this what the screw looks like?

You will probably have to grab the screw head with something, and try to twist the screw out.  Do a Google search on this.

If I'm right and Jack's screws aren't anything like the tamper-proof screws shown above, then drilling them out and trying to use an easy-out will just make things worse.

But I wonder if the screw heads are big enough and accessible enough to get in there with a Dremel tool and a worn cut-off wheel (the smaller diameter the better) to use the cut-off wheel to cut a slot in each screw head to get a regular screw driver in there and spin them out.

That's all I've got, without seeing a photo of the screws.

Mr. Dumb-ass here with an update.  Well the two screws were part of the old turn signal switch and were never necessary to remove to get the old switch out.  As was mentioned above, the switch is held in by just a simple Phillips head screw at the left side of the switch.  Everything is great now, new switch works perfectly.  My powers of observation really suck.  Thanks for everyone who chimed in with suggestions---much appreciated.
