Tooling: Modulo screwdriver heads.

[kwikfix328]

Do any of you Pro's bother buying these specialist Modulo type screwdrivers. They seem to be a cross between a Phillips/Pozi drive and a Plain slot drive.

I have noticed that more and more electrical screws seem to have these hybrid heads on them though. I'm increasingly finding that it is often takes a bit of experimenting to see see which type of scredriver works best in these screw heads, Slotted, Phillips or Pozi drive.

Is it worth investing in a couple of new Modulo screwdrivers ?

I have two.
I still use normal irazola ones.
But do final check with the big one before fitting the board cover.
The smaller one is very good for smoke detector bases and small din rail contactors.
I do not use them for everything as they seem to wear fast.
I think there are two versions, one is pozi and there is the crosshead, so make sure you get the right type

I got mine from RS they were dearer, but the bigger one I got looks more heavy duty than the one at TLC.

excellent , just to complicate things even further .

I think i shall add this to the bottom of my list of things to do now, but thanks for the input.

Its easy , the tlc are proberly the right ones.

Even normal cross head drivers are different
One is like a "X"
the other is like an "X" but has extra grooves
Think one is pozi and one is phillips.
In uk one seems more popular than the other ,
Some people call them pozi drivers, even when there not.
I will try and sort the part numbers so you can compare.

Worth having,if only to impress your mates

the Phillips design is about 70 years old, I think it is obsolete now.

Pozidriv screws have the extra "X" marked on the head so you can tell they are not Phillips. It allows you to apply more force. If you put a lot of force on a Phillips it tries to push the screwdriver out of the screw head.

Not in the Aircraft industry they're not , very much alive and kicking, along with many others, although mostly Phillips, Torq-set, Tri-Wing, Hex and Dzus.

The only screw head types that I have 'never' seen fitted to an Aircraft are Pozi drives or these Hybrid Modulo things, which is why i don't have a 'free' stash of them.

Phillips screws are still surprisingly common in their use. Drywall screws for example.

I have a couple of CK modulo screwdrivers, and find them reasonably easy to snap the bits designed for the slotted head part of the screw off.

Maybe I'm just a but of a rougharse though?

Might need one of these to comply with the 17th.
