Complete Kit with Convenient Storage Case: The set includes a complete assortment for various needs: 6 M4-M6 inserts (12 and 15 mm), 6 M6-M8 inserts (12 and 15 mm), and 6 M8-M10 inserts (12 and 15 mm). They are supplied in a clear plastic storage box (7.2 x 6.5 x 1.7 cm) for organized and easy-access storage. 4. Enhanced Stability and Robustness for Assemblies: Designed with a deep, regular, and clean thread, these inserts act like a helical spring once installed. They significantly increase the strength of the assembly, evenly distribute tension on the threads, and effectively resist shock, vibration, and shear forces. 5. Simple Installation and Long-Lasting Performance: Use is intuitive: the insert is screwed into the damaged hole to create a new, standard, and robust internal thread. This solution increases the thread's resistance to fatigue and corrosion, reduces wear, and thus significantly extends the lifespan of the entire bolted assembly.
