6.4. Cut Thread Tolerances

The threading dies presented in our catalog are designed for cutting the most common and basic for a given type
of thread tolerances: for metric thread 6g, for threads UNC, UNF, etc., 2A. On individual request we can
manufacture threading dies for other, than the above mentioned, fields of tolerance, e.g. for the metric threads: 4h
for tight threads, 6e for threads to be covered with thin galvanized coating.
