<<Features of Machine Screws>>
Externally threaded fasteners with relatively small diameters and a formed head.
Used in combination with tapped components or nuts.
Common head types include pan head, flat head, oval head, truss head, and bind head.
<<Flat Head Features>>
The shape resembles a deep plate commonly found in households (though not like today's rounded - edge dishware).
Used with countersunk holes (chamfered in a conical shape) so the head sits flush with the surface.
Often selected when there is a need to keep the fastener head from protruding - either for functional reasons (e.g., another part sits on the surface) or for appearance.
<<Applications>>
No specific application - widely used in carious settings.
Designed for use with a Phillips scredriver.
