Threaded wooden rods – special sizes
During restauration work, it is not uncommon to come across threaded wooden rods which do not conform to our modern standard sizes. We can produce a tap for you in  these special-sizes, but require a sample thread first.  These special-size taps will enable you to make your own die in order to reproduce threaded rods.
