Question:

I have an Eagle tri-axle trailer with 14” aluminum wheels. I will be installing 1/2-20 conical lug nuts etrailer Chrome Trailer Wheel Lug Nut - 1/2 - Qty 1,Item # 12CLN-L. Any suggestion on torque and whether to use any kind of lubricant such as an anti-galling grease or just leave them dry?

Expert Reply:

For the 1/2 inch lug nut # 12CLN-L and the 14 inch aluminum wheels you will torque each lug nut to 75 to 85 foot pounds. No lubricant is required. However, since this is on a boat trailer and the hub studs are likely raw steel a little lube would help keep corrosion at bay. There isn't a specific product I would recommend since they all do about the same job.

If you need a torque wrench we have # ALL944001 which is a basic torque wrench rated from 10 up to 150 foot pounds.
