UNC Hexagon Re-Threading Die Nuts
Our range of UNC hexagon re-threading die nuts is designed for cleaning and restoring damaged external Unified National Coarse (UNC) threads. These die nuts are primarily used for thread maintenance and repair rather than cutting new threads.
UNC threads feature a coarse pitch and are widely used in American and imperial fastener systems across engineering, automotive and industrial applications. The hexagonal design allows the die nut to be used with a standard spanner or socket for controlled thread restoration on bolts and studs.
Browse the selection below and refine by UNC thread size to find the correct hexagon re-threading die nut for your application.
