Same items entered in SO and PO are not displayed in DO and PR while pulling it from respective document

We need to supply fastners along with our main product. Each main product requires same fastners and hence they are recorded multiple times in Quote.
While converting Quote to Sales Order these repeated items are not displayed. Sr.No. for those items is also not seen in Sales order item table.

When quote runs in 400 line items its difficult to manually track such missed items.

Please provide some solution. Same issue occurs while converting SO to DO and DO to Invoice. As well from Material Request to PO and Purchase Receipt and Purchase Invoice.

How many different fasteners are there, and how are the classified - as variants? If main item always ships with fasteners would a product bundle work?
