HARDWARE
Periodically, the vehicle should be inspected for loose fasteners. Fasteners should be tightened in accordance with the
Torque Specifications table.
Generally, three grades of hardware are used in the vehicle. Grade 5 hardware can be identified by the three marks on
the hexagonal head and grade 8 hardware is identified by 6 marks on the head. Unmarked hardware is Grade 2.
