A2 M3 X 16 Socket Button (Dome Flange Head) Screws A2 Stainless (304)

A2 flange socket buttons are used in applications where a clean, low-profile look is desired and the fastener needs to be corrosion-resistant, such as in mechanical assemblies, sheet metal fabrication, and automotive components. They are also used for holding softer materials, protecting surfaces, and for decorative purposes. The A2 stainless steel material is chosen for its corrosion resistance, and the flange distributes the load over a wider area.
