Install the Toilet Seat (cont.)
Align and place the base of each metal hinge over the toilet seat
mounting holes.
Insert a bolt from the underside of each toilet seat mounting hole
up into the base of each metal hinge.
Thread the plastic nuts on the bolts from underneath the toilet
seat mounting holes. The plastic nuts should be flush against the
underside of the toilet seat mounting holes.
Hold the plastic nuts in place with an adjustable wrench while
tightening the bolts with a flat-blade screwdriver.
