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 fasten-
ers 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 tightness.
The torque required to loosen a fastener averages 
75% to 80% of the tightening torque, depending on 
the condition of the contacting surfaces.
On light gasket jobs, run each fastener down to a 
relatively light torque and use a hand torque wrench 
for fi nal tightening.

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-
