Thread-Repairing Die Nut Sets

The dies in these sets match the width of hex nuts that are the same thread size, so one tool can turn both. For tight spaces, use with a ratcheting wrench since it requires minimal clearance to turn. Repairing dies remove imperfections and rust so threads engage properly for a strong connection.
