PIR Screw

[kathekas]

I have been careless and dropped the screw and lost the screw which secures the lens to the case.

What do other people use as a good substitute?

Usually nothing, it won't come off, it snaps on doesn't it?

They are normally self tappers

Take another one out (carefully) and use it to compare

Thanks everyone good advice.

The detector is placed in pretty inaccessible place and I had difficulty removing the screw.

The problem was my stupidity.
