A machine screw is a type of screw that is commonly used in industrial and manufacturing applications to secure components within engines, electronic products and general machinery.
Raised countersunk machine screws are similar in design to standard countersunk machine screws, the difference being that they are designed so that the top portion of the head is slightly raised above the level of the substrate.
This type of machine screw has a raised countersunk head with a slotted recess for installation with a flat-bladed screwdriver or bit. Such fittings can commonly be found on light switches and electrical plugs.
