Description
Slightly turn the expansion bolt clockwise to prevent it from moving freely.
Before hammering the expansion bolt with a claw hammer, take a nut with
the same specifications as the nut of this expansion bolt and turn the nut
until the top of nut is flush with that of the expansion bolt to avoid damaging
the thread during hammering.
Hammer the expansion bolt into the installation hole with a claw hammer.
Fasten the nut near the expansion tube clockwise to allow the expansion bolt
to fully expand.
Loosen the nut counterclockwise and remove the nut, spring washer, and flat
washer in turn for use during subsequent installation.
