I like Friadent because their impression post screws also has the option for hex and slot like this healing abutment.
I cannot tell if the coating/laser color coding has worn off, but for a regular 3.8mm is yellow, and the 4.5 is blue.
This does not seem to have color, or just worn off from repeated use.
One thing that might help, is that the hex driver needed is the 0.90mm (or 0.035").
Very useful when pt has limited opening.
