Today I was dissasembling my HP laptop. Some of screws i saw first time. I didn't find it on web ant it is too small to make a picture. Screw head is 5 milimeters in diameter and 8 milimeters long. In the middle of the head is hexagonal hole but, there is slot screw drive across head of the screw.
Which type of the screw is that, and which screwdriwer to use?
