Hardware
Periodically, the vehicle should be inspected for loose fasteners. Fasteners should be tightened in accordance with the
Torque Specifications table.
Use care when tightening fasteners and refer to the Technician’s Repair and Service Manual for specific torque values.
Generally, three classes of standard hardware and two classes of metric hardware are used in the vehicle. Grade 5 hard-
ware can be identified by the three marks on the hexagonal head and grade 8 hardware is identified by 6 marks on the
head. Metric hardware is marked on the head with 8.8 or 10.9. Unmarked hardware is Grade 2.
