Size of nuts for heater box and fan
« on: August 20, 2014 - 05:11:53 PM »
I'm missing a couple of nuts, and being east of the Atlantic, it's not so easy to get the imperial threaded nuts as it is for you guys in the US.
I can buy online though.

So I'm wondering, what size/type of thread should I look out for when getting a nut for the heaterbox studs going through the firewall?
And for the fan studs, what size/type of thread is that?

Thank you!
Is this the heaterbox stud?

I imagine the fan stud will have a fine thread.

Yes your right, the fan studs are 10-24.
