My leaf spring bracket finally arrived. I ordered the part from Ford and it came with (grade 10.9) 12mmx x 1.25 (fine thread) bolts and nuts. Unfortunately, there was no torque instructions. I have looked online and have found a fairly wide range of torque values (75 - 100 ft-lbs). Those values depend on if they are dry, zinc plated, oiled, etc. The bolts that came with the bracket have some kind of aluminum pigmented coating. A torque calculator online gave me 88 ft lbs for an aluminum coated bolt. I also find that nuts seem to have a lower torque requirement. The nuts that came with it are also crimp style lock nuts which typically have a higher torque requirement.
Should I just shoot for in the middle of the range I found and hope for the best, or does anyone have some actual torque numbers that would work for these bolts and nuts?
