Felt stupid but we are always learning

Talking to a service engineer on site recently and he had a screwdriver I'd never seen before (15 years in trade) luckily neither had a other guy I work with in fact it was mixed some had seen them others had not anyway they where. PZ/SL drivers and fitted absolutely perfect into various items.

I'm looking to get a nice slim line insulation one so I can fit into all terminals if people can recommend ?

They're also known as 'plus and minus' drivers.

Yes, also called 'modulo' by some manufacturers as well.

Aye, and technically PH/SL not PZ/SL (just in case you search and wonder why you get no results)

You get both philips and pozidrive versions of them in several sizes as well.

My apologies, only came across the ph type and have spent a good while searching for suppliers.

It would help enormously if the damn manufacturers would all use the same naming convention but they don't so it's a real slog to find them. I'm actually wondering if they're available in a Supadriv version as well although I've never seen them.


**edit** Here's what Supadriv looks like for those who haven't seen them.

I can't believe the big local distributors don't stock them. I would have thought these items would be in fairly decent demand by sparks.

I have both the WIHA and WERA sets that come with a handle and inserts. I would recommend the WERA now as the WIHA inserts have tendency to pop out as they are secured via a slider thing half way down the shaft, whereas the WERA set push into the handle.

It sounds silly but in practice it is very easy to push the locating sleeve into the dislocate position thus losing the bit from the handle. Also, in the WIHA set, the handle grip is quite round and smooth, making a good purchase grip on the handle more difficult than on the WERA set.

On a final note, I personally go by the description of plus/minus for the type of combination head you are referring to.

Many may disagree, but I find that to get a proper grip on many of the manufacturer's terminals, these are a must for any toolbox in order to get a decent, tight, sound termination, without mashing up the screw head.

They are handy in some applications, but with them being a PZ/SL usually a PZ or a SL will do the job just as well, which may account for lack of demand ?

what's wrong with an impact driver? plenty of grip and loads of torque. far quicker as well. :59:

The problem I have with the plus/minus screwdrivers is they're prone to the tips breaking the first time you use a philips plus/minus screwdriver in pozi plus/minus screw and vice versa. You've got to be really aware of using the correct driver for the correct screw every time.

And also known as Modulo drivers.

(Oops, sorry Marvo. Just noticed you have already said this!)

I think that's a brand name CK give to their plus minus drivers.

I think you're probably right as I've only seen the CK ones called "Modulo".

Shame that whoever wrote the description for Screwfix didn't understand what they were selling. I've found this a lot with Screwfix's descriptions; some are total garbage.
