Under Dash Vent - Mount Screws For Pull Knob

[Richie G]

Silly question but as I put everything back together I can't seem to find the right screws for the bracket that holds the pull knob for the under dash fresh air vent.  I went through two boxes of old junk screws to even see if i can find a match but no luck.  Anyone know what they are?  They seem to be self threaded like some kind of sheet metal screw but nothing i have wants to bite and stay tight without tearing the threads.  or is it some odd machine thread?  i don't seem to feel a nut behind it or see any type of machine threads like most of the bolted connections.

Not so silly, They are a sheet metal screw for some reason, about 2cm long I can't determine a thread pitch, but course is the appropriate term. 

They thread right into the bracket.

Thanks so much. I'll hit the home depot and grab an assortment bag.

 

Could these M5 be it

Maybe these are a bit more economical shall we say if you are not concerned about originality in this application

I’m not positive if these are the exact correct size (they have many other sizes), and you have to provide a flat washer, but they will serve the purpose.

Thanks. Not too concerned about originality for these four screws was just trying to find something that described the size and thread so that either walking in the Home Depot gives me a head start or I can search the web. I appreciate the link
