Baffle Attach Screws

[tx_jayhawk]

I've had a problem where I've lost (presumably through vibration) a couple of the baffle attach screws that go from the side of the baffles to the cylinder head (O-360 engine). They are coarse thread with phillips head, around .75" or 1" long (going off memory, not at the plane).

Does anyone have a spec. for that screw, and/or any suggestions to keep them in place?

Don't know if the picture is clear enough. I think you are talking about the screws listed above.

I kept loosing the rearmost screw on the #4 cylinder. So did a friend with an RV-8. We both have carb'd O-360s. I now use a 1 inch long pan head, drilled head, and safety wire it.
