[TenTec] urgently need to find some hex head screws

[Barry N1EU]

I'd greatly appreciate any help finding a handful of the hex head screws
widely used in the Corsair/Omni series.  They were used to hold down PCBs
as well as the aluminum shield plate in the Omni 6 etc.  They have a hex
head with a screwdriver slot and the thread is slight tapered like a sheet
metal screw.

Does anyone have some extra screws or know where I can order some?  I need
4-6 screws urgently.

Thanks & 73,
