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.
