Torque Adapters
Torque adapters or extensions extend
or reduce the reach of a torque wrench.
The torque adapter,(Figure 13), is used
to tighten a fastener that cannot be
reached because of the size of the
torque wrench head, drive, and socket.
If a torque adapter changes the effective
lever length the torque reading on the
wrench will not equal the actual torque
applied to the fastener. It is necessary to
calculate the torque setting on the
wrench to compensate for the change of
lever length. When using a torque
adapter at a right angle to the drive
head, calculation is not required,
because the effective length has not
changed.
Pliers
Pliers come in a wide range of types
and sizes. Pliers are useful for holding,
cutting, bending, and crimping. Do not
use them to turn fasteners. Figure 15
and Figure 16 show several types of
useful pliers. Each design has a
specialized function. Slip-joint pliers are
general purpose pliers used for gripping
and bending. Diagonal cutting pliers are
needed to cut wire and can be used to
remove cotter pins. Use needle nose
pliers to hold or bend small objects.
Locking pliers (Figure 16), sometimes
called Vise- Grips, are used to hold
objects very tightly. They have many
uses ranging from holding two parts
together, to gripping the end of a broken
stud. Use caution when using locking
pliers, as the sharp jaws will damage the
objects they hold.
