Impacting Techniques
The longer a bolt, screw, or nut is impacted, the
tighter it will become. To help prevent damaging the
fasteners or workpieces, avoid excessive impact-
ing. Be particularly careful when impacting smaller
fasteners because they require less impacting to
reach optimum torque.
Practice with various fasteners, noting the length of
time required to reach the desired torque. Check the
tightness with a hand-torque wrench. If the fasteners
are too tight, reduce the impacting time. If they are
not tight enough, increase the impacting time.
Oil, dirt, rust or other matter on the threads or under
the head of the fastener affects the degree of tight-
ness.
