Torque limited impact socket

[Andrew]

Has anyone used one of these -

Preset to max. 100Nm (74ft-lb), upon application will disengage at 100Nm (max).

Plastic sleeves prevent wheel rims from scratching

Rubber end stops prevent tops of wheel nuts from scratching

Remove the wheel nuts with full torque capacity from the Impact Gun. TLS Socket will unfasten to full torque delivery of the impact gun. Select from the range of TLS Impact Sockets.

To tighten wheel nuts, add TLS Socket to Impact Gun. Place socket on wheel nut and begin to tighten with Impact Gun. The socket will tighten wheel nut to max. 100Nm (74ft-lb), once this torque is reached the TLS socket will ‘slip’ and disengage the Impact Gun, preventing the wheel nut from tightening further, reducing the risk of being overtightened.

To reach the vehicle manufacturers torque setting (refer to the vehicles user manual), apply a Kincrome Torque Wrench to tighten to manufacturers specifications. Ensure the wheel nut is fastened securely.

Am I missing something here?

It tightens it to 74 pounds.... then you still have to use a torque wrench to finish the job????

How accurate are they?
If you drop it and how do you calibrate it again?

I've had wheel shops use them on my wheels before so I guess they work. Still prefer the old fashioned method.

The place that does my alignment makes it a rule never to use airtools on wheelnuts.

Sorry to hi-jack this thread...

... but has anyone had any experience with any $60-$90 electric impact wrenches? How good are they?


Impact Wrench

New. 1/2\" drive. 12 volt outlet connection. Includes two double ended sockets. Impact resistant housing. Blow moulded carry case.


Repco has the above on sale for $69.95, and I'm considering at getting one. Any particular feature and/or functionality that I should have as a must?

I'm looking to using it when I change over the wheels on my 5 from road to track wheels etc. Plus on odd occassion removing my 4WD wheels.

Any advise anyone?

Ive used a snap on one that I was pretty impressed with, dunno if the cheap ones stack up.

Can the electric ones muster up enough grunt to say take off stiff suspension bolts etc?

Good thread about various brands here

I had thought same thing too untill we purchased a Hitachi cordless impact wrench. It has a lot of torque and enough charge for a full day's use on the RX-7 down at the race track. I would not purchase no cheapy to do it though. I am thinking of going Dewalt for myself which has a bit more torique than the Hitachi.



Back on topic - Snap On Tools also do a similiar thing

BTW, anyone know what is the head size on a MX-5 wheel nut? (NA6)
