Groetchen Pikes Peak

Post by geordy55 »

I’m looking to see if anyone has the long bolts that connect the Pikes Peak top to the base. If not, then does anyone know what thread it is? I’m suspecting 3/16 UNC, but need confirmation if possible.

Why not get a thread gauge? It's a very useful item when repairing old arcade machines. I use mine a lot when I can remember where I put it. A cheaper way is to buy a nut of the type you think it is, but this is not foolproof if you have guessed wrong.

I’ve got my own engineering business and have taps and dies of every thread imaginable, but can’t seem to confirm this thread.

geordie55 This link may be helpful to find your thread size.

I'm sure we are all familiar with the American UNC and UNF threads in imperial sizes but this thread range extends far beyond the threads that are commonly used in the UK.
This link to the full list of threads may be helpful. Some American nut & bolt suppliers will supply to the UK but the cost can be expensive.
