Common Bolt Torque values

Checking Bolt Torque

The tables shown give correct torque values for various 
bolts and capscrews. Tighten all bolts to the torque 
values specified in the table, unless indicated otherwise. 
Check tightness of bolts periodically. 

IMPORTANT!  If replacing hardware, use fasteners of 
the same grade.

IMPORTANT!  Torque figures indicated in the table are 
for non-greased or non-oiled threads. Do not grease or 
oil threads unless indicated otherwise. When using a 
thread locker, increase torque values by 5%.

Bolt grades are identified by the bolt head 
markings.
