I have no idea what the torque spec on your bolt should be but looking at the torque table in Zinn and the Art of Road Bike Maintenance, it looks like 300 inch-lbs should be safe but your mileage may vary.
Proximo, thanks for your response,
Yes square tapered spindle. Think I will try as you suggest. I thought of doing this at first but I read somewhere the metal aluminum is self lubricating and it is not necessary. I will use a torque wrench as well. I did find a "Bicycle Torque Specifications" list
here: but the torque is only listed for a crank bolt not a nut. I would think a nut would have a lower torque.
Thanks again,
