General description These self-tapping threaded inserts are designed for easy installation without the need for pre-existing threads. They are ideal for use in low-strength materials such as aluminum and magnesium, effectively preventing thread damage while enhancing connection performance. These inserts are particularly useful for parts that require frequent disassembly, significantly improving the service life and wear resistance of the thread. They also help prevent screw loosening, making them suitable for applications that demand a high safety factor. Additionally, they facilitate the repair of damaged screw holes, allowing for normal use and preventing the loss of parts. Technical specifications Quantity: 20 pieces Type: M4 x 8mm Other information
