How to Handle BOM Items in Separate Stock

Hello experts, I have an open-ended question about how to handle a stock situation. Apologies, but I am new to SAP and my company does not have good training available for this.

My facility is largely intended for sales and service, but my small team does some production work. So, we have a stock room, but it is not really intended for doing production orders and we don't want our stock keeper to have to manage small parts. I want all the materials to be included on the BOMs and I would like all the materials to have master data in SAP so that purchasing can happen easily. However, I would like to keep things like screws, nuts, and washers in my team's area and manage our own stock and pull those parts as needed for production. I am looking for advice on how to do this properly.

If I simply check the "Bulk Material" box in MRP2 in the material master, I think that may work, but how will inventory be tracked in that case? Will I need to ask our facility's stock manager to manually update stock occasionally? Are there any other problems I might be missing?

Alternatively, is there a way to handle this situation within the BOM instead of the material master? What are the drawbacks of such an approach?

Thanks for your help!
