HOW TO USE:
- Identify the Correct Size: Select the thread restorer die that matches the size and thread pitch of the damaged bolt or stud. The sizes are clearly marked on each die.
- Clean the Fastener: If possible, lightly clean the threads with a wire brush to remove any loose dirt or debris before beginning the repair.
- Apply Lubricant: Apply a small amount of light oil to the damaged threads and to the inside of the thread restorer die. This will help reduce friction and ensure smoother operation.
- Engage the Die: Carefully align the selected thread restorer die with the damaged threads. Begin turning the die onto the bolt or stud by hand, ensuring it starts straight and does not cross-thread.
- Use a Wrench/Socket: Once the die has started squarely, use a standard socket or wrench on the 6-point external hex of the die to gently turn it down the length of the damaged threads. Apply steady, even pressure.
- Clean and Inspect: Continue turning until the die has passed completely over the damaged section. Remove the die, clean the threads again, and inspect them to ensure they are properly restored and free of nicks and burrs.
