the holes or get stuck
inside the part.
❻Make sure you
understand which
hardware will be used on
each step.Using the
wrong size of screw, bolt
or pin might strip the
threads or cause damage
to the part in which it is
being used.
❼To avoid
misalignments, always
leave the screws loose
and tighten them until
all pieces are
positioned correctly.
❾Sometimes the laminate might cover
partially or entirely the hole on apanel.If there
is no visible hole for the screw, pass and press
the tip of your finger over the area where the
hole should be located to feel the indentation,
and once found, carefully pierce the laminate to
reveal the hole underneath.
❿If the hole seems too small for the screw,
first make sure you are using the correct size of
screw and that it’s been installed in the correct
hole.If the hole still appears to be too small,
carefully pierce the laminate to reveal the
hole’s actual size.
