Metric Fastener Torque Chart - Kioti KL701 Manual

TORQUE TIGHTENING CHART 2
Note : Use these torques, unless special torques are specified. Values are for UNC and UNF thread fasteners, plated or unplated
as received from supplier. Fasteners can be dry or lubricated with normal engine oil.
Values do not apply if graphite, moly-disulphide or other extreme pressure lubricant is used.
ISO Class No.

Because of the low ductility
of these fasteners, the torque
range is to be determined
individually for each application.
As a general rule, the torque
ranges specified for grade
10.9 fasteners can be used
satisfactorily on 12.9 fasteners.
* M14 is not a preferred size.
