Bolt Torques - Walinga Airlock 1008 Operator's Manual

BOLT TORQUES

The critical required torque values for the airlock fasteners are identified in Table 8-3. For any fasteners not specified in Table 8-3,
refer to Table 8-4 and Table 8-5 for imperial and metric bolt torque requirements respectively. Check the tightness of bolts
periodically. Replace any damaged or lost hardware with the same strength fastener. Torque values indicated in the following tables
are valid for non-greased or non-oiled threads and heads. Unless otherwise specified, do not grease or oil bolts or cap screws. When
using locking elements, increase the listed torque values by 5%. Reference Figure 8-11 and Figure 8-12 for proper grade
identification.
