Bolt Torque Chart - Frontier LS2011 Operator's Manual

• Torque values listed are for general use only, based on the strength of the bolt or screw.
DO NOT use these values if a different torque value or tightening procedures is given for a
specific application. For plastic insert or crimped steel type lock nuts, for stainless steel, or for
nuts on u-bolts, see the tightening instructions for the specific application.
• Fasteners must always be replaced with the same grade as specified in the manual parts list.
• Shear bolts are designed to fail under predetermined loads, always replace shear bolts with
identical grades.
• Make sure fasteners threads are clean and start thread engagement properly.
