WARNING
EQUIPMENT FAILURE
The torque value for bolts and capscrews are
identified by their head markings. Replacing
higher “Grade” bolts (Grade 8) with lower
Grade bolts (Grade 5) will lead to equipment
failure and can result in injury or death. Always
use replacement bolts with the same Grade
markings as the removed bolt.
