Socket Flange Button Screw
A socket flange button screw is a type of fastener that combines a rounded, low-profile head (button head) with an integrated flange and a hexagonal socket drive. The button head provides a smooth, finished appearance, while the flange spreads the load over a wider area, reducing the need for a separate washer.
