NOTE
○ When driving screws in steel studs, use the genuine
Hitachi steel stud screws in Table 1.
If any other screws are used, they may not drive properly.
○ Using them may cause improper driving (come out,
sticking up) or damage (strip the bit or head of the screw),
so do not use any screws but those specifi ed.
* Come out: Bit fails to engage with the head of the screw,
thus spinning out and failing to screw into the material.
