## Horizontal Screws

Horizontal screws are used to attach the plate on the side. At the moment, it is only possible to place screws on [plate walls](#plate-wall). Enable screws with the `horizontal_screw_wall` option. This requires `plate_wall_thickness` to be set for the relevant wall. The screws will be placed in the middle of each cell.
Horizontal screws are used to attach the plate on the side. Enable screws for individual edges with the `horizontal_screw_wall_north`, `horizontal_screw_wall_east`, `horizontal_screw_wall_south`, and `horizontal_screw_wall_west` options. The screws will be placed in the middle of each cell.

Similar to vertical screws, the screw head can be customized with `horizontal_screw_countersink_top` and `horizontal_screw_counterbore_top`.

The exact hole position can be adjusted using `horizontal_screw_offset`. By default, the hole will be centered on any wall.
The exact hole position can be adjusted using `horizontal_screw_offset`. By default, the hole will be centered vertically on the plate or any wall.
