TIGHTENING TORQUE FOR MAIN COMPONENTS
When you want to find out a suitable tightening torque for a bolt, first determine thestrength division of the said bolt, using the table below. Then, locate suitable tightening torque in the tightening torque table described later. As for the tightening torque for a nut, find out suitable tightening torque in the same way as with the paragraph 1 above, based on the mating bolt. Tightening torque posted in the service manual is a standard value for steel fasteners. lt is, therefore, necessary to modify these tightening torque when you tighten fasteners made of materials other than steel. This rule also applies to such instances where bolts are undergoing heat or other stress, such as
vibratory loads and so forth.
METHOD TO IDENTIFY STRENGTH DIVISION OF BOLTS
1. Identification Method by Checking Bolts Themselves
