Cheese Head Slotted Screws
Cheese Head Machine Screws have a round cylindrical head with a flat top, usually have a slot drive. Slotted screw heads are perhaps the oldest and most common variety; a linear slot in the head accepts a standard screwdriver, which is also called a flat-head screwdriver. Machine screws have finer threads than wood screws. They are designed to be used in conjunction with a nut or tapped hole.
