Teng part numbers are systematic — once you know the pattern you can decode most of the range:
Family first — the leading digits identify the product family (for example 6005xx are combination wrenches; the last digits are the size, so 600517 is the 17 mm).
R suffix — ratcheting version (600517R = 17 mm ratcheting combination wrench).
RF suffix — ratcheting with a flexible head.
RK suffix — repair kit (1192P1000RK fits the 1192P1000).
Set numbers — tool sets and trays have their own series (TT, TC, TED prefixes for trays and kits).
Every spec article on this help center lists the full part-number table for its series. If you have a number you can't place — even a competitor's — ask us in chat and we'll identify it.
