Temperature Sending Units- Any specific torque?

[Fiat88]

I bought two new ones to put in while I have the coolant drained, how tight should they be threaded in the engine head? Thanks.

I don't think there is a torque for that. but there sure could be. I just go a bit beyond snug towards firm, but stop before i think somethings going to strip or break. I guess after installing 100k of iron pipe you get to know what feel is more than anything.
