INTRODUCTION
Torque - Nominal tightening torques for normal assembly
NOTE: In the metric tables, nominal sizes M4 through M8 hardware torque specifications are shown as a Newton
meters (pound-inches) numerical value.
Nominal sizes M10 through M24 hardware torque specifications are shown as a Newton meters (pound-feet) numer-
ical value.
Metric hex head (non-flange) hardware
Plain (PLN) – an unplated hardware finish with residual manufacturing oils
Zinc-dichromate (ZND) – a yellow colored chemical plating formula yellow applied to the hardware
