Lock-tight recommendations?
(OP)
I’ve got to attach a copper plate onto a piece of steel with 4 screws. The plate is there solely to stop any damage being done to the steel.
The component is part of a deep sea tool, and the copper plate will be in contact with Panelin control fluid, and temperature (Probably max 250 degrees C).
The screws holding on the plate are M8 screws, but these cannot vibrate or work themselves loose at all.
So, I’m looking for a lock tight solution that can be inserted into the holes before the screws are inserted. The screws must be able to be removed if needed, so this lock tight solution cannot be fully permanent.
Have you got any suggestions as to which solution might work best?
Thanks,
Graeme Mathieson.

The designer said that locking heli-coils were not feasible.
Thanks for the link.

Will there be an issue with corrosion (steel & copper)?

RE: Lock-tight recommendations?
I'm not sure about the corrosion, it is something I will flag up with the engineer who asked me to look into this.
Heckler - Those spirallock's look very useful. I'll see if that can be used instead.
Thanks,

The plate is brass, not copper. I put copper by mistake in my first post.
