47mm Wheel Studs arrived, struggling to fit them

The wheel studs arrived - 47mm long, so I tried to fit some;

First brute force - hammer, then vice with a socket over the thread, then after cooling in the freezer. The first one is just vice + hammer, the second the same method after cooling in the freezer (not much difference):

At this point the vice was fine, however my bench & the vice mounting was moving, and I was at the limit of torque I could physically put into the vice.

Posted the query on RHOCAR - looks like the best option is to wind the studs in with an open wheel nut on upside down - Ordered same on Ebay. (arrived 29/6/12)
