Early half shaft grease fitting size ?

[Flamingo 5]

I need exact size not part number 

im trying to locate a generic version 

[Hans]

why not replace the U-joint?

[Simeon]

You mean the Zerk fitting in the joint? RealOEM lists that as M8x1 thread (as it lists the threads for all threaded parts /hardware). 

 

And the part number is http://www.realoem.com/bmw/enUS/part?id=2552-USA-02-1968-114-BMW-2002&mg=33&sg=25&diagId=33_0880&q=07119960640

 

You are welcome!

Thanks for your reply 

the reason I didn’t need the part number? Just the size was because I wanted to call around and locate localylocals

M8?  That’s huge for the hole size.  I would have guessed M6.  CM8x1, how could the threads be only 1mm?

And M8 x 1 is a "fine thread" pitch for 8mm diameter.  Normal thread  pitch for an 8mm bolt is 1.25 mm.  May take a little searching, but they're out there.  The head studs on my model 500B Fiat Topolino are 8 x 1.25 where they screw into the block, and 8 x 1.0 for the nut end.  Go figure.  Even the French use the same threads on both ends of their studs!

PS--The only 8 x 1.0 bolt I know of on a 2002 is the drain plug on the radiator lower tank.
