Our airplanes were made by the Mooney Screw Company.

The only reason for our planes is that they needed someone to sell the screws to!

I am beginning to think that! Lol!

Be careful if replacing these with larger screws or a screw and washer.  If I remember correctly these hinges fold over on itself and the thicker screw/washer may not let it close completely without putting the door under a lot of extra stress.

All fixed.  #4 PK and blue loctite.  I replaced two of the eight screws with aluminum rivets just to make sure they don't come loose again.  There were several screws in the other door looses as well.  Took all those out and loctited those as well.

Now I shall await the next thing to fix....

Don't get creative with the screws. Just order from the parts manual.

Disagree.  Those little #4 screws and tiny thinnerman nuts are too chintzy.  This is my nose gear door with stainless 6-32 machine screws and locknuts.

As you can see, there is no interference with either side of the hinge.  And my nose gear doors close very tightly.

Thousands of Mooney' have flown and continue to fly safely with them, as long as they are installed correctly.  I would guess that the #4 PK screw is as strong if not stronger than a #6 stainless screw.

I agree.  I'm simply glad of the security of the locknuts on the back side.
