Our range of BA hexagon re-threading die nuts is designed for cleaning, restoring and repairing damaged external British Association (BA) threads. Unlike circular cutting dies used for forming new threads, hexagon die nuts are primarily used for re-threading and thread maintenance applications.
Manufactured to suit BA thread specifications, these die nuts are ideal for restoration work, classic engineering, instrumentation and legacy equipment where British Association threads are commonly found. The hexagonal shape allows use with standard spanners or sockets for controlled thread restoration.
Browse the range below and use the filters to refine by BA size to find the correct hexagon re-threading die nut for your application.
