heet metal mechanics, removing a stripped screw from an aircraft can be a
knuckle-busting exercise.
So save your knuckles and hopefully the airframe by using the right screw
extractor for the job like it says in Para 4-20 of TM 1-1500-204-23-9. One option is
NSN 5120-01-398-2868. Unfortunately, that extractor is a Class II item and you’ll
have to cough up a whopping $458 to purchase it!
However, you can Fnd extractors in the new common aviation tool system (CATS).
There is an extractor in the sheet metal tool kit, NSN 5180-01-628-2376. There is
also an extractor in your sheet metal shop set, NSN 4920-01-600-7364.
Another way is to cut a line in the screw head with a hack saw and use a ±at tip
screwdriver to remove it. Problem is, the saw blade could contact the airframe during
the cut. And there’s always a chance the screwdriver might slip, gouging the airframe
and busting your knuckles.

Just remember, when removing
stripped screws the
best
option
is the one that results in
no
knuckle or airframe damage.
the extractor
is in this kit.
That usually means letting an
experienced
sheet metal person
handle the job of removing a
stripped or broken screw.
When a screw gives you a problem,
stop
before
it strips. Call the
sheet metal folks and let
them
handle the problem screw.
So here’s a
little advice
for you
mechanics.
I
can get
that stripped
screw out!
I say we do
it the
old
fashioned
way!
Waitaminit,
guys! maybe
you should
call in the
sheet metal
experts!
