I am a maintenance mechanic for a large trucking firm. On 4 oct 2011, I checked the torque on the 5th wheel bolts of unit 11054 because I could see that the 5th wheel was sliding on the frame. The bolts were defective - yielding prior to reaching the recommended torque of 236 ft.Lb. I adjusted the torque wrench to 200 ft.Lb., Its lowest setting, and could not get any of the bolts to hold. I replaced all ten bolts with 5/8" grade 8 hardware instead of the factory 16mm 10.9 Metric because that was all we had available.
