• RESTORE DAMAGED THREADS - Taps and dies quickly reshape and clean damaged or corroded internal or external threads to reduce downtime and return equipment to service.
• FOR INTERNAL OR EXTERNAL THREADS - Taps thread into nuts or internal threads on equipment to quickly clean out corrosion and debris and realign threads. Dies thread over external threads on bolts, screws and studs to restore threads, extend the life of fasteners and ensure proper installation and torquing.
• SAFE ON EXISTING THREADS - The thread restoring design will remove burrs, nicks, debris and corrosion without the risk of damaging or cutting into existing threads.
• EASY TO USE - Once started by hand, use a wrench to run the thread restorer in and out of the threads, quickly cleaning and renewing them.
• MADE IN THE U.S.A.

NOTE: Not for use on hardened threads or to cut new threads.
