Torque Values for Standard Metric Fasteners
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 āCā 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
weld nuts.
Markings on bolt heads or nuts indicate material grade ONLY and are NOT to be used to
determine required torque.
