Perma-Kee Kits provide a reliable solution for repairing stripped or damaged threads in all types of metals and applications. Each kit includes a high-speed steel (HSS) drill, HSS tap, installation tool, and two to four Perma-Kee inserts. These solid, one-piece Perma-Kee inserts ensure a secure and permanent thread repair. Once installed, locking-kees are driven into the surrounding parent material, preventing rotation caused by vibration or torsion. No special taps are required, making installation straightforward and efficient.
