I guess non of you guys have ever seen the inside of a car assembly
I retired a few years ago after 30 years in the car assembly plants,
high speed screw guns walk on two feet and nowadays hardly any screws
are used on the cars anymore, it's all plastic mouldings with studs
moulded on, that are hammered into body holes with steel clips in them,
we used to screw a-post, b-post and if there, rear door mouldings and
doglegs on the car with screws, also the roof and drip rail chrome
strips would be screwed down and inside the windshield and backlight
mouldings where screwed on to keep the cloth, and later covered
cardboard headliners up and cover up the rubber around the glass.
Screw guns, air driven and high speed were and are used to instal
screws, by assemblers, and we had several differand style mostly #2
phillip screw tips, to fit the screws, some with small ribs almost like
serrated, and magnetic holders, because you would not want the tip to
come out of the screw, and damage a chrome and later mostly aluminium
and also if you where installing for instance a coat hook and slipped
out push that screwtip through your finger.
We used wads of soft tar to stick the screw tips in to get rid off any
small metal slivers on the tip.
Some of the guys would be installing mouldings that kept the vinyl up
around the door openings put in several screws, while also holding the
moulding in place on every car, and at 60+ cars an hour have any idea
how long a tip would last if you would let it torque out ?? and people
would not be happy with screws that have skin cutting edges on them. O
well this is enough, If you don't know what you're talking about, ask,
or go and find out, there is enough BS out there already.
Have fun and take care
