Fasteners should be replaced with the same or higher
grade. If higher grade fasteners are used, these
should only be tightened to the strength of the
original.
Make sure fasteners threads are clean and that you
properly start thread engagement. This will prevent
them from failing when tightening.
Tighten plastic insert or crimped steel-type lock nuts to
approximately 50 percent of the dry torque shown in
the chart, applied to the nut, not to the bolt head.
Tighten toothed or serrated-type lock nuts to the full
torque value.
