Rowland I was at one time a Snap on tools dealer and Snap on used to
produce a chart for use with torque adaptors for use in this situation ie.
any adaptor offsetting the torque length as used on for example . V12 Jag
cylinder heads when the casting overhangs the head bolts . the angle that
the torque wrench is pulled makes no difference (unless someone corrects me)
any Snap on dealer should be able to supply the chart . Philip George
