These screws are designed with a scientific and practical structure, combining multiple functional advantages to solve common problems encountered in fastening operations. The flat head design ensures that the screw head can be completely embedded in the material surface after installation, achieving a smooth and neat appearance without protruding, which is especially suitable for scenarios that require aesthetic consistency, such as furniture surface installation and decorative panel fixing. The Phillips square hole drive is a dual-purpose design, which can be used with both Phillips screwdrivers and square screwdrivers, enhancing operational flexibility and avoiding slipping during tightening, effectively protecting the screw head and the connected material from damage.
