 I have come to realize that if it threads into aluminum on our bikes, its probably whitworth. Being that its a more course thread, it wont strip out of aluminum as easily as BSC.

 I have a feeling I bought some of those with hex-socket ends maybe in stainless at the local 'nuttery' (Nut 'n Bolt shop), which is handy but not so good if rivet counting :!

 I wish I would have been so smart. Getting that screw out with the gearbox in the bike is not a lot of fun.
