TORQUE SPECIFICATIONS
CHECKING BOLT TORQUE
The tables shown below give correct torque values for various bolts and capscrews. Tighten all bolts to the torques 
specified in chart unless otherwise noted throughout this manual. Check tightness of bolts periodically, using bolt torque 
chart as a guide. Replace hardware with the same strength bolt.

Torque figures indicated above are valid for non-greased or non-oiled threads and heads unless otherwise specified. Do 
not grease or oil bolts or capscrews unless specified in this manual. When using locking elements, increase torque values 
by 5%. 
* Torque value for bolts and capscrews are identified by their head markings.
