Help for a Mechanical Idiot...

I am installing (going to try anyway) the passing lamp spacer and the instructions in the tech library call for 2 3/8" NC x 3/4" bolts.

 

What does the NC stand for. I've never seen this expressed. I don't want to buy the wrong thing.

My guess is that the 2 is a qty of two bolts, 3/8" is the diameter of the thread, NC is the type of thread National coarse, and 3/4" is the length.

 

 

NOT sure why those would be Imperial and not metric though ??

Thanks.

 

I take it to mean that I should by the 3/8 - 16 instead of the 3/8 - 24.

Yes, buy the 16 instead of the 24.

 

16 thread per inch, 24 threads per inch.

NC is a reference to USS thread, NF refers to SAE thread.

Did you get the spacer from BMW if so it comes with all the bolts in the package? Its a 10min job, just roll up a big bath towel and stick it in between your forks to support the lite bar and keep it off your fender. Craig
