Interesting. It may be hat the engine vibration is doing the unscrewing
when the nut is hot. I think I would try to drill it for a safety wire.
That is what safety wire is suppose to fix. See if you can get a angled
hole through one side.
Just my thoughts. My EGT probes are the clamp on type (912S) and I had
to weld a boss on the pipe to prevent it from cracking.

Subject: Europa-List: EGT Sensors
Hi all,
I have an unusual problem. I have two EGT sensors installed, one on
the front port exhaust and the other on the rear starboard.
The probes and the mounts were supplied by Grand Rapids. The probe
mounts are simple screw in devices with a compression gland to secure
the probe. They are made of brass. The problem I am having is that
every 50 hours or so the rear gland unscrews itself. When I install it,
its is really tight to screw in, but it still comes out. I have
replaced it 3 times but it hasn't made any difference, the darn thing
still eventually unscrews. It never happens to the front pipe, which is
cooler than the rear one.
Anyone have any ideas on what to do ?. My first thought is to try and
get one made out of stainless steel so the co-efficient of expansion is
the same.
Thanks, Paul
