Correct, I've found it difficult to get the originals for the 2a, but I figured early on that if I get the UNF equivalent (or very close) for everything, at least if they need replacing later it shouldn't be too difficult. :BigThumb: You would have to be a true Landy die-hard to notice the difference in most cases ;)
Purists, relax, I've retained the originals! :p

I found the same thing ... if I'm willing to buy a box of 500/1000 - depending on what it is - it's all good. I just don't need that many! I must say, the local bolt supply shop has been excellent at supplying UNF equivalents though. Some need trimming down (length-wise) but so far it's all worked out well :BigThumb:

Some advice for those unfamiliar with thread systems and fasteners. Do not mix fasteners with differing thread angles. People will tell you that Whitworth and UNC are "the same". They are not. Whitworth form threads have a 55 degree angle whilst Unified form is 60 degree. Whilst BSW and UNC will screw together with the exception of 1/2", this is not good practice. Mismatched thread angles cause crushing of the crests of the threads and have self-loosening characteristics. Nor will they maintain set torque.
Angles are:- BS series 55 degrees
UN series 60 degrees
Metric (all sorts) 60 degrees
BA 47.5 degrees
