RJ & Sons micro taps and die plate


Recommended Posts

They are certainly not a brand, but probably a watchmaking supply house. We had a similar discussion in another thread a few days ago. Watchmaking threads do not fit neither into the metric nor Imperial threading systems. So you will not find easily any hardware, screws or nuts, to go with them.

 

Personally, I would not use such threading plates for two reasons: if one frequently thread-size becomes worn, you have to replace the whole plate and they are more unwieldy to use than individual dies. These plates were primarily designed to work-over damaged screw-threads - you just screwed down the screw into the plate, not to cut completely new threads. Another application was to cut a short new thread onto a piece of brass wire held in a pin-vice, e.g. when repairing the hinges in pocket-watch cases.
