A man who knows his screws.
Boom, done, no argument.
And he's probably right.
Most common relay racks for holding electronic equipment have mounting holes in the uprights tapped for 10-32 screws (although there are exceptions). In many places people use whatever sort of screw is available - round head, pan head, binder head and others. As a result of years of experiences, I am now recommending that the preferred screw for holding equipment in racks be the Bud Industries part number 7346 screw.
