BOLT TORQUE INFORMATION
DECIMAL HARDWARE
1.
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.
2.
Make sure the fasteners threads are clean and that thread engagement is started. This will prevent them from
failing when being tightened.
3.
Tighten plastic insert or crimped steel-type lock nuts to approximately
50 %
of the dry torque, applied to the
nut, not to the bolt head. Tighten toothed or serrated-type lock nuts to the full torque value.
4.
The L9 (Alloy) fasteners torque values are for a bolt, nut, and two washers. When using L9 (Alloy) fasteners,
do not use the values in this table for tapped holes.
