Okay here you go...
The four screws for the clutch slave are listed on realoem.com as 11147678478, ISA screw, M6X20. The screws holding the side cover to the engine case are seventeen 11137676132, ISA screw, M6X25 and three 11147678478, M6X20 which also hold the heat shield, for a total of 20 fasteners.
Grainger.com shows item 36RH95, A2 stainless (alloy type 304) M6x20, hex head, DIN 933, $25.37 for a pack of 50 (51 cents each), and item #6BB27, A2 stainless M6x25, hex head, DIN 933, $16.91 for a pack of 50 (34 cents each). Odd that a longer screw is cheaper...?
But a pack of 50 is only enough for two bikes. Want larger quantities, go to (for instance, no affiliation) fastenersuperstore where item 549597 is a carton of 2,000 M6-1.0 x 25 mm Machine Screws Torxģ Button Head 18-8 (A2) Stainless Steel screws will cost $206.28 or a measly 10.3 cents apiece. Note that 18-8 stainless is the same as Type 304.
Such costs illustrate what we already know: BMW parts prices are f'n outofthisworld, even for common industrial fasteners (Al vs SS aside).
Now if you're Down Under, shipping becomes an issue and another net search is in order.
