An electric version it is about £30 and it slots into the socket of the socket set and then the other side you attach the normal socket. Set it to the correct setting ( digital display) start turning and it verbs quicker the closer you are to the setting until you get a constant tone your at the setting.

I don't think Gee is talking about the measurement of recorded torque at the socket wrench head Rob. When you put an extension bar onto the wrench head that allows you to reach further into where a nut or bolt is located that is when then figures change and the formula comes into effect. When you normally use a torque wrench it's handle to drive to socket (no long limbs to flex) when you add a reach bar this will have it's own elasticity that will absorb some of the force required to do the nut/bolt up when it 'twists'. To get the correct torque setting in the correct place you must factor in the twist and compensate for it.
GEE, THE FORMULA DIDN'T TRANSFER IN THE COPY AND PASTE.
yith a lot of socket sets you will get a small, medium and large extension bar, not for levering but for reaching. This is the thing you need to take into consideration.
