Impacting Techniques
The longer a bolt, screw, or nut is impacted,
the tighter it will become. To prevent dam-
aging the fasteners or workpieces, avoid
excessive impacting. Smaller fasteners re-
quireless impactingto reachoptimum torque.
Impacting for two seconds is generally
sufficient for a 10mm bolt and one second
for a 8mm bolt. 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.
