Tip: Installing/Removing screws without boogering the heads
Those 8R8 screws [just for example] are very soft and the Philips slots get mangled pretty easy, especially if you use an electric drill driver and don't get a good set on them first, or their just too darn tight.
Do this:
- Get a tube of Permatex Valve Grinding Compound at auto parts store.
- Dab a tiny bit of the compound on the screwdriver tip
- This will help the driver tip to stay in the Phillips Head slot without slipping out whether tightening or loosening the screw.

Good tips, and I'll add another - buy GOOD screwdrivers and/or bits. It is amazing how well a properly built Phillips can grip a screw!

Paul's right. Snap-On bits have gripping ridges that help, and some Craftsman screwdrivers have diamond dust coating the tip.

A dab of toothpaste on the tip will help with stubborn screws also.

I've got a few good Snap-on Phillips bits too. They work great for removing Phillips screws. I don't use them for inserting, because I replace with Robertson or Torx heads...

Better yet is to replace them all with 6 lobe drive (Torx) screws.

I bought some #6 torx SS screws and found they actually stripped out easier that the AN phillips head. Maybe the SS ones are just too soft. I was both surprised and disappointed.

German quality
Check out the Wiha brand screwdrivers at http://www.wihatools.com . They've supplanted my previous favorite brand Snap-On.

I always put a rub of Boelube on the threads of new screws. There is no need for the threads to have that much resistance in the nut plate. If you just find ways for the screw driver to bite the head without easing the stress in the threads you will start breaking the screws off. This issue is a downside to having a cowling with no hinge pins but hundreds (feels like it) of #6 and #8 screws.

You can try ever so slightly tightening the screw to "break it loose" then remove it.
