INSTALLING BLIND FASTENERS
Before installing blind fasteners, verify the location of wiring, air-
bags, sense wires, etc. so you don't accidentally damage something
important.
Slip a washer on the 5/16-18 x 2 1/4 in. bolt, and pass them through
the 9/16 wrench and installation tool as show at right. Place a drop
of oil on the 5/16-18 bolt before threading on the blind fastener.
Place the blind
fastener through the
hole and use the 1/2
in. wrench or socket
to tighten the bolt until
the blind fastener is
fully seated.
As the blind fastener
"bulbs-out" it will get
easier to turn until
it bottoms out and
"sets". Make sure that
the blind fastener and
installation tool do not
turn during installation.
