I'm trying to find a vent screw that will fit my 2019 Slingshot Wizard. It's good that both Slingshot Australia and America (hood river) have them available for sale on their websites

(sarcasm). I found this alloy Chinook one on Surf Sail Australia's website. The description says it will fit a 10mm vent hole. I can't accurately measure the vent hole of my board as it's recessed into the deck, but the thread of my vent screw is either 10 or 11mm. (clarification on this would be appreciated). If it's 10mm does that mean the the board vent hole is also 10mm and the chinook screw will fit? I know this might sound like a stupid question as how does 10mm fit into 10mm but there might be some thing i'm not aware of re thread specs. Does anyone know? Also, are the Goretex ones on Simmer Style WA's Website ok for SS Wizards?
