Does the All-In-One come with screws for mounting?

No it doesn’t. The right choice of screws for a job depends on the material in which the screws are to be driven (e.g. wood, steel or aluminum). Therefore we cannot be sure to provide the most suitable screws.

Furthermore, most screws that are provided with a product are often thrown out because such provided screws tend to be of poor quality, so even if we provided an assortment of high-quality screws, they would probably end up being thrown out.
