Maintenance section Torque Specifications Torque for Standard Bolts, Nuts, and Taperlock Studs Metric Hardware 1 1 Newton meter (N m) is approximately the same as 0.1 kg . m. 96 Most of the nuts, bolts, studs, and threaded holes in NOTICE your lift truck are metric. In this manual we provide specifications in both metric and U.S. customary The two charts below give general torques for measurement. Always replace metric hardware with bolts, nuts, and taperlock studs of SAE Grade 5 metric hardware. See the parts books for proper or better quality. replacement. NOTE : For proper fit, use only metric tools on metric hardware.
