Metric Fasteners
The following Table lists torque values
for standard hardware and are intended as a guide
for average application involving typical stresses
and machined surfaces. Values are based on
physical limitations of clean, plated and lubricated
hardware. In all cases, when an individual torque
value is specied, it should be followed instead of
values given in this table.
Replace original equipment with
hardware of equal grade.
