Next time I would use hinge and abandon the screws altogether. Looks nicer and faster to get the tips on and off. Agree though that #4 are way too small. I even wear out the heads of a few #6's every time I take off the tips.

I have read others that have NEGATIVE comments about the #4 screws. After almost 16-years and 2,700 hours of flying, I have yet to have a problem with any of my #4 screws.
I always use a driver drill with removal high quality tip bit, or a screwdriver with a high quality removable tip. If using a non-power operated driver to remove the screw, the screw driver is usually a "Snap-On" ratcheting screwdriver.

I found that the screws that came with the cleveland tool kit stripped very easily. I tried everything including flattening the tip on a high quality new screw driver tip to get a deeper bite in the screw head-- still stripped.
torx is the way to go.

Yes, I did that! Torx are not perfect in these small sizes, but they are definitely better than Phillips!

For those of you using stainless screws, a dab of beeswax in each of the nutplates will make the screw easier to remove, and helps in the stripped Phillips head arena. Stainless tends to gall in the nutplates and becomes hard to remove.
If using a power drive run at slow speed also.
Toilet bowl sealing rings are a prefect source of beeswax----one ring should last you a lifetime------Jay Pratt excepted

That (beeswax) is what we (former employer that had Aircraft in its name) used on the thread of the screw. We just pulled one side of the screw thru the wax then ran it in. "DoAll" and other solid waxes work just as well from using what ever I had laying around over the years when Bee's Wax was not at hand.

That's kinda gross. Do you just set the toilet on some 2x4's while your using the ring?

Seriously, since I first saw this done, I don't understand why it's not the standard way to attach wingtips. Still considering if it would be possible to retrofit mine.

Only thing with the hinge is you have to take out the slop inherent with hinge. Simple to do with a hammer and anvil to stretch the hinge on one side so it fits tight.

I'm too clumsy with a screw poker, so went the hinge route.

OK, so who is going to be the first to write me an illustrated guide to the hinge method for Kitplanes?
You can PM me if interested....
