When attaching a replacement stud, it is recommended that the stud be tightened by turning it lightly by hand (finger) so that the stud is perpendicular to the female thread side, and then finally tightened with a dedicated tool (stud wrench).

 

If a special tool (screwdriver) is used for installation from the beginning, avoid putting too much load on it or putting it in with a twisted diagonal. The screws may not properly engage with each other and may break apart.

 

※Because the screw pitch is an overseas standard, once the screws are crushed, they cannot be repaired.
※Also, kindly refer to the instruction manual that comes with the product.
