Information and Specifications
TORQUE SPECIFICATIONS: METRIC FASTENERS
The following table lists torque values for standard hardware. It is 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 cases when an individual torque
value is specified, follow that specification, instead of values given in this table.
Replace original equipment with hardware of equal grade.
