Flange button head socket screw

Flange button head socket screw is a type of bolt with an integrated flange and a low-profile rounded head with an internal hex socket.

Advantages:

① Improved anti-loosening performance

• The large bearing surface helps distribute pressure, reducing surface indentation.
• The integrated design prevents loosening at the interface between the bolt and the washer area.

② Higher assembly efficiency

• The large contact surface allows for larger mounting hole tolerance.
• No separate washer is required, reducing assembly steps and simplifying installation and part management.

③ Reduced number of components

• Eliminates the need for a separate washer, reducing the total number of parts in the assembly.
