11.0 BOLTING TORQUE VALUES
At intervals of not more than six months, check the tightness of all bolting. The
recommended torque values for all bolting are shown below:
Torque (ft-lb)
Part # Description Size Material Nominal Maximum
233
Yoke Clamp Nut 3/8-16 A194-2H 35 45
| 234 Gland Stud Nut 3/8-16 A194-8M 6 15
240 Handwheel Nut 1”-8 AISI 316 25 50
NOTE: The above table provides nominal design torque values and maximum
torque values using an assumed friction coefficient of 0.2. The maximum torque
values provide for material conditions such as rust and oxides that exist after
equipment is in service.
