Using an impact driver - rattler - to tighten MCBs!

[Marti]

Noticed one of the old hands doing this recently; using an impact driver (rattler) to to tighten the slotted PZ2 screws in a newly installed board. Never occurred to me that you could but when I (very discreetly) checked them with a conventional screw driver they were all spot on.

Does / has anyone else done this or am I the last one one the bus,'cos it certainly saved some time? Can you actually buy a slotted PZ2 head for an impact and how'd you line up the slot - normally done by feel before you actually apply any torque.

I'll get me ticket now

I would never put that kind of impact on an device or the board. I am in the back seat with you.

I just use the slotted PZ2 interchangeable blade from my wera set in the drill.

None of my searches have given up a slotted PZ2 impact bit and a standard PZ2 will chew up pretty quickly leaving the next guy or gal to sort the mashed heads

 

[ruston]

yes you can get them . I think The sheds do them . I have used them in a Milwaukee impact driver on large roofing joists .

It is a plus/minus head or PZ/S.

I'm not a fan or user of impact drivers although I know a lot of sparkies nowadays use them for fixings and drilling.
It's definitely not the right tool to tighten terminals for sure.

I have however used a small battery driver (non impact) on a very low clutch setting to just to wind breaker terminals in, and that does save a bit of time on a large DB. I have always done the tightening of terminals with a hand tool after this though.

Not a chance. Something needing 2.5 Nm torque and a machine capable of more then 100Nm placed on it? What could possibly go wrong? Maybe I’ve misunderstood?

Wiha make them SL/PZ2

And how will the MCB/RCBO/RCD handle the vibrations caused by using this method?

Using a impact driver what next ,you could pick up a torgue driver from a garage.

It's the old expression about an open mind and what you let in Personally I was one of the last to get an impact. They are too powerful for many of the tasks we perform.

Thanks for sharing your thoughts.

So many times ive come to boards where they've rattled them in. Far too tight almost round out the screws on the Neutral and earth bar when trying to unscrew them. Im not a fan of it

I work for a power tool accessory manufacturer. My boss asked me if we needed to produce a Plus/Minus impact driver bit as he noticed that that was one of the ones not in our range.

I said "No"

Butchery that's what it is Butchery, an impact driver for terminations, use a hammer and chisel instead, dreadful practice.

You wouldn't approve of a lump hammer and large flat screwdriver to tighten a large SWA gland nut then ?

Asking for a friend.

Yes, but that's a different situation Andy (and Friend)

No to the impact driver, but I am interested in a weak willed wizzy winder to help with my poor aching joints. Any suggestions welcomed .
