I dont say correct. But how many have the better MCB screwdriver. ?? You defiantly get a better torque on the screw with this one.

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 1730722385471.pngbits 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.
 
I use them all the time, they come in different sizes and as 1/4" hex bits.
They are FHP1/FHP2/FHP3 when I order them.
Ebay does them, they last long enough for me.

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.

I DEFIANTLY do have them and automatically aim for one when working on MCB's
 
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.

which panel lights do you find troublesome?

of LED's and the old tranilamps require a PZ1, the biggest issue being the screws didn't always line up with the holes.
I found the Klockner lamp and switch blocks fiddly but used a 4mm flatty

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.

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 first came in a bundle and initially I had no idea what it was...

No problem with that!

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.

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.

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.
