If the tool or screw are misaligned, the
screw will not drive into the work sur-
face or it will not drive straight.
2. Pull the trigger and push the tool for-
ward with a "punching" motion to sink
the screw into the drywall. A punching
motion will engage the snap-action
clutch, cause the screw to start rotat-
ing, sink the screw and disengage the
snap-action clutch within a fraction of
a second. If pressure is not maintained
on the tool after engaging the snap-
action clutch, the screw will not prop-
erly seat.
The snap-action clutch will automati-
cally disengage and the insert bit will
stop rotating once the screw has been
driven to the selected depth.
These screwdrivers feature a snap-
action clutch, which may ratchet slightly
when the screw is sunk to the selected
depth.
NOTE: Practice driving screws into
pieces of scrap material to become
familiar with the tool and the snap-
action clutch action before attempting
to drive screws into the workpiece.
3. To remove screws, remove the locator
assembly and switch the forward/
reverse switch to the reverse position.
Reattaching the locator assembly will
not change the depth setting.
Driving Self-Drilling Screws into
Cold-Formed Steel Framing (Fig. 9)
For Screwdrivers Rated 0-2500 RPM
When working with light gauge sheet metal,
20 gauge and thicker, follow the same pro-
cedure as with wood studs. See "Adjust-
ing Locator Assembly" for setting driving
depth.
The screw may hesitate slightly when it
finishes breaking through the drywall and
starts to penetrate the sheet metal. This is
normal. Remember to use a "punching"
motion to drive the screw and keep firm
pressure on the tool until the screw is
seated.
Self-drilling and self-tapping screws drill,
tap and fasten in one quick, easy motion
without a separate drilling operation. Their
unique design works in metal up to 1/2"
thick, giving a strong, reliable hold. The drill
point ensures rapid drilling and consistently
low drilling pressure while the drill flutes
remove drilling chips. The pilot section en-
sures that drilling is completed before the
first thread engages the material. These
screws can be used in many applications
as shown at the right.
The depth setting is very important. See
"Adjusting Locator Assembly" for setting
driving depth.
