i would consider that almost a catastrophic failure. a catastrophic failure can happen to a Herpstat and your snake can die as a result.

Understood but Im not a gambling man
I also have Large panels. 24"Lx15"D. I would never use just a screw myself.
I hear ya about failures even on our Tstats.. but I figure at least I have the Safety shut down & you can double up on Tstats too hahahaha
