The large head with the knurled grip allows the screw to be tightened or loosened with minimal external force. This feature makes the screw an ideal fastener for any device that require frequent assembly/disassembly. They are commonly used to fasten safety covers of electronic devices. They are typically inserted and tightened into pre-drilled tapped hole ad are used when a low profile is preferred. These screws are available in steel as well as stainless steel A2 and A4.
