I get trade discount too...so you prob save £40 on the one on ebay all told after all with snap on your paying for the name in comparison thy are just as good as each other. vinny's right the draper one's good too also comes with calibration certificate if im thinking of the right one
To do hub nuts you need a 1/4 inch wrench and the cheapest I could find one was £70 from my local tool shop.
at the end of the day you can tell how tight to do a bolt. There are not many bolts on the car that really need torquing down.
A simple 8mm bolt will not require that much effort to shear it so common sense & some threadlock could be used.
Meanwhile head bolts and wheel hub bolts require more attention..
And they had a torque calibrator to test it?
