TORQUE TIGHTENING CHART 2
Note: Use these torques. unless special torques are specified. Values are UNC and UNF thread fasteners,plated or unplated as received from
engine oil. Values do not apply if graphite, moly-disulphite or other extreme pressure lubricant is used

Because of the low ductility of
these fasteners, the torque range
