Replacement screws for Bosch gas range (base to burner)

I need to replace the original T20 torx screws (2 per burner) for my base to burners on this Bosch range.

Can't find replacements...Bosch doesn't sell any hardware. I read that sheet metal screws are not good for this attachment because they could strip the cast aluminum that the burner is made of.

Need help here..thanks.
