Bolt Torque / Tools Required - Yetter 500 Series Operator's Manual

Important:
tightening. Tightening hardware beyond the recommended range can reduce its shock
load capacity.
All hardware on the 5000 Devastator is either Grade 5 or Grade 8, unless otherwise
noted. Grade 5 cap screws are marked with three radial lines on the head. Grade 8 cap
screws are marked with six radial lines on the head. If hardware must be replaced, be
sure to replace it with hardware of equal size, strength, and thread type. Refer to the
torque values chart when tightening hardware.
The chart below is a guide for proper torque. Use it unless a specified torque is called out
elsewhere in the manual.
Torque is the force applied to the end of the handle or cheater bar, times the length of the
bar.
The following table shows torque in ft-lbs for coarse thread hardware.
