Hexagonal Flange Cut-off Screw is a special fastener that combines a hexagonal head, flange surface and cut-off design, with multiple advantages and application scenarios. The hexagonal flange cut-off screw consists of a hexagonal head, flange surface and cut-off design. Its head consists of two parts, the hexagonal head and the flange surface. This design makes its support area to stress area ratio larger, can withstand higher preload, and has better anti-loosening performance. The cut-off design enables the screw to better cut the material during installation and increase the fixing effect.
