Original equipment standard hardware is defined as coarse thread metric class 10.9 bolts and
class 10.0 nuts and thru hardened flat washers (Rockwell “C” 38-45), all phosphate coated and
assembled without supplemental lubrication (as received) condition. The torques shown below
apply to phosphate coated bolts designed for 60 % yield strength.
The torques shown below also apply to the following: phosphate coated bolts used in tapped holes
in steel or gray iron; phosphate coated bolts used with phosphate coated prevailing torque nuts
(nuts with distorted threads or plastic inserts), phosphate coated bolts used with copper plated
