I have pair of NOS aluminum crank bolts that somehow ended up with a Campy bottom bracket I bought from a fellow forum member some time ago. They were made by Sugino, and they look to be of high quality, compared to some I have seen before. Question is do they "work"?? I know that you use a steel bolt to seat the cranks on the spindle first, then use the aluminum bolts just to keep the cranks from backing off the spindle. But will the aluminum bolts take the everyday riding stresses that the crank will excert on it?
I guess I just want to know whether I should use them or just keep them as a weenie curio from the past and keep them away from my C&V bikes??
