Thermocouple 330mm for M5 & M8 Gasolec Heater

Thermocouples are delicate items, if they are tightened too much the contact points can easily be damaged.
The correct way to do this is:

Tighten the nut on the thermocouple as much as one can by hand

Then use an 8mm spanner to turn the nut 60deg, or 1/6th of a turn more.
