Torque screwdriver !!!!!

Have an Armeg set on the van, it is very shiny.

I have a Wera interchangeable screwdriver set which comes with two handles?
Have thought about swapping one of the handles for the torque wrench adapter, but £70 is a bit much for something I’ve never used.

Okay they don't say you are to use a torque driver but how else are you going to achieve it, being devil's advocate here we all bang on about how you mustn't mix manufacturers mcb's, what is the difference between torque settings and pick and mix mcb selection, is one worse than the other?

Assuming someone isn't such a klutz that they can't spot busbar alignment or type incompatibility, mix'n'match means you lose type approval, and then there's 536.4.203.

As for torque settings, I guess you have to decide what you understand by "Manufacturers’ instructions shall be taken into account".

Ah - but this time an update with a valid point about a regulation which was new and not in force at the time of the thread ?

One of the bits of kit I'm installing at the minute is made in Mexico and the DC power studs are #10-32 with a recommended maximum torque setting of 2.26Nm.

I haven't snapped one yet as I'm using my torque driver but the customers own installation teams have snapped two off meaning each unit has to be sent back to the factory on Mexico to be repaired...

Glad I bought it now as it could get a bit costly snapping them off...

No minimum?

Just do them finger tight, then, and you'll be bound to be below the maximum.

No, but seriously - that's a madly exact figure, arrived at by some brain-dead conversion process with no concept of ± to some sensible metric value. If accuracy down to 10‾² Nm was really necessary then they'd have to specify adjustments for temperature. I bet that any value between 2.15 & 2.35 would be fine.

Are they from Mexico too?
