Flat Head
Countersunk aerospace screws engineered for flush, aerodynamic installations.
MAC flat head fasteners are designed for applications requiring flush surface integration, aerodynamic continuity, and consistent countersink geometry.
These NAS and MS standard screws are commonly used in airframe skins, access panels, fairings, and interior assemblies where clearance and surface smoothness are critical.
