Hardware - Cushman AC TUG Owner's Manual

HARDWARE

Generally, three classes of standard hardware and two classes of metric 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. Metric hardware is marked on the head with 8.8 or 10.9. Unmarked hardware is Grade 2.
Periodically, the vehicle should be inspected for loose fasteners. Fasteners should be tightened with care and in
accordance with the Torque Specifications table or as specified in the Repair and Service Manual for this vehicle.
Unless otherwise noted in text, tighten all hardware in accordance with this chart.
This chart specifies 'lubricated' torque figures. Fasteners that are plated or lubricated when
installed are considered 'wet' and require approximately 80% of the torque required for 'dry' fasteners.
