I dont say correct. But how many have the better MCB screwdriver. ?? You defiantly get a better torque on the screw with this one.
I think it was more that with a Philips/pozi/straight driver they can slip out of the mcb fuses screw. Dont get that with the above.More torque is not always good, today retired, so not a problem, but in the days of servicing equipment, the torque screwdriver was the only way to ensure you did not neck off wires, when testing for tightness.
If I want some thing really tight, then View attachment 361617bits are used in battery powered drivers, some times impact type, god help anyone with a hand held screw driver what ever the end it like, trying to remove them.
which panel lights do you find troublesome?They (ph2/pz2) can slip out of more than MCB screws.
I use pilot lights a lot in control panels, the screw slots on them are often way too shallow so using a FHP2 is a must.
The way I see it - the top one is a Philips, apart from the unequal slot lengths, but a Philips driver probably OK.I dont say correct. But how many have the better MCB screwdriver. ?? You defiantly get a better torque on the screw with this one.

Well I think others may have different opinions, before I got my first FHP screwdriver I would have most likely made the same comments as yourself.The way I see it - the top one is a Philips, apart from the unequal slot lengths, but a Philips driver probably OK.
The bottom one is Pozidriv. The right driver in each feels solid, the wrong one feels wiggly.
No problem with that!Well I think others may have different opinions,
Now you are familiar with it, what's special about an FHP screwdriver? Does it work properly (ie no play) in either of the 2 in the OP's pic? Of course with Philips and Pozi the right driver should be used, if it's at all tight.initially I had no idea what it was...
Apart from some very old versions it has fitted every MCB so well that all of the 'bad fit' of PH & PZ screwdrivers simply feel wrong.No problem with that!

A definite case of the right tool for the job. and one where I aim for it in the toolbox in the same way I'd aim for a spanner for a nut rather than a pair of pliers or five holes.
I'd like to make the same claim but probably only 15 years in my case.Yes, have had them for a very long time.
