Does anyone know the thread size on the Spirit 310 thermometer? I lost mine while doing a deep clean. (I thought I’d screwed it back onto the gauge after removing it, but it dropped off while moving the parts from the yard to my bench. Despite a thorough search in 109 degree Florida sun, I can’t find it.) a trip to Ace didn’t help. 3/8-16 baulks early as does M10. Are these a special thread pitch? I can buy a new one, but I’d like to save the original if I can.Thanks in advance for any help.
