2.4 Tightening Hexagon Socket Head Cap Bolts
Hexagon socket head cap bolts are used in places where mechanical strength is required.
(A hexagon socket head cap bolt will be called a “bolt” in this manual.) These bolts are
fastened with the tightening torques shown in the following table.
When it is necessary to refasten these bolts in some procedures in this manual (except special
cases as noted), use a torque wrench so that the bolts are fastened with the appropriate
tightening torques as shown below.

Do not fasten all bolts securely at one time. Divide
the number of times that the bolts are fastened into
two or three and fasten the bolts securely with a
hexagonal wrench. Then, use a torque wrench so
that the bolts are fastened with tightening torques
shown in the table above.
