As above

 

I'm missing 4 of these for my Porsche Adaptors :cry:

 

12 x 1.5 x 30 Socket Cap (Asked chap in shop to tell me what it is)

 

Can someone explain the 3 figures to me :cry: :cry:

 

Or even better where can i get them :D

12 = thread size M12

 

1.5 = thread pitch 1.5mm

 

30 = thread length 30mm

 

Not sure if they are a specific material for this application. I'm sure a google search should come up with something.
