Advantage
Constructed from 316 stainless steel, the repair insert nuts have better stability, corrosion resistance, oxidation resistance, strength, and heat resistance, and does not rust when working in humid environments compared to 303 stainless steel. Even in challenging environments, they maintain optimal functionality and longevity.
Instruction
The surface of these thread-reducing nuts is smooth, with deep and clear threads that distribute force evenly. To facilitate installation and removal, each thread-reducing nut has a slot at the top for accommodating a flat head screwdriver, making it easier to screw them in.
Note
If there is a stripped M4 thread and you wish to continue using an M4 thread, you can use this method to expand the M4 thread to M6, and then recover it back to M4 using the repair nut. Reducing the diameter and utilizing stainless steel material, will make the M6 thread stronger.
