The head of the slotted raised countersunk head wood screw is semi-sunken and has a single slot on it. It can be tightened with an ordinary screwdriver. The threads on the screw are relatively thick and the spacing is wide. This enables it to grip the wood more firmly when being driven into it.

Slotted raised countersunk head wood screws are classic wooden fasteners.They have a slightly arched, grooved top, but a sloped bottom that allows them to sit flush with the wood. This slight arch provides more headroom than flat-head countersunk screws, making them less likely to crack soft wood when tightened.
Slotted countersunk wood screws are commonly used to secure hardware to nearly flush wooden surfaces. They have a slightly raised head and a deeper slot than flat-head countersunk screws, preventing loosening. They are suitable for cabinets, door panels, and various other woodwork applications.
Slotted countersunk head wood screws drive threaded screws into wood. The raised head is not very high; it is just a subtle curve above the surface. The sloped bottom bites into the wood, making the head flush with the wood.
The major advantage of slotted raised countersunk head wood screws is that they fit securely into the wood. The coarse-thread design can firmly grip the wood, making it less likely to loosen. It is also convenient to remove, and unlike nails, it won't cause damage to the wood when pulled out. After being screwed in, the head will not protrude too high and will be basically level with the surface of the wood.
