In some cases, however, grounding to sheet-metal may be the only choice. To
properly use a sheet-metal screw, locate a hidden area where two of the vehicle's sheet
metal panels are overlapped and welded together. After
ensuring that there is adequate depth behind this spot,
drill an appropriate-sized hole. A Drill Bit or a good
quality Self-Tapping Screw may be used. Wrapping a
length of adhesive tape around the Drill Bit will reduce
excessive Drill Bit penetration. At this point, grind
the surface of the metal around the drilled hole, as
the goal is a bright, clean contact area for
the ring terminal. A Carbide Burr Bit or a
Mandrel and Cut-Off Wheel may be used
in a Drill or Die Grinder to accomplish this
quickly. Caution: Use proper eye protection!
Since the screw is being run through two layers of
metal, some thread cutting must occur. A Screw-
gun or Cordless Drill is very handy for this
operation, as the screw may have to be ran
in and reversed several times. Once the
screw can be fully and tightly threaded
into the hole, the star washer and a
ring terminal are put on the screw,
and it is securely tightened. A good
practice to increase the longevity of the
chassis ground connection is apply a
protecting coating of silicone sealant over all of the parts.

Grounding The Black Wire To Sheet Metal.
Running the screw through two layers
of sheet metal allows more threads to
contact the metal, which reduces the
chances of the screw to strip out or be-
come loose. Grind the surface until
the metal is shiny and clean.
Avoid trying to drill through the
spot welds, which are harder than
the surrounding metal.
