Standards, executions and application
The drive combines a slot with a Pozidriv recess. Use the matching tool and check the bearing surface of the wide head. Do not confuse this type with double-slotted Poeliers screws: two slots do not constitute a PZ recess. The flanged version documented by Berardi is a variant to specify by drawing; it does not imply a separate washer.
