Completely smooth and roundish like a philips screw without the "+"
like manufacturing missed a hit to put "+" impression into blank
heads. Yes, I saw how nails and bolts, screws were made on canadian
shows called "How it is made".

Yes, I have a screw of that break away type with carb rebuild kit
for (my first car) caravan plymouth 1987 2.2L 4 cyl with carb.
Fixing caravan up in "major" ways, again a first for me but I
have done bit of auto work on other friends'. Yes, that is last year
for carb! Later half of 1987 saw moving up to 2.5L with single
injection in throttle body (TBI) and multi-injected V6 3.0L. Not
using that break away screw, don't want more problems trying to get
it off again later. Reason: the carb has broken choke heater and
needs a rebuild and bit of repair that former owner screwed up.

Question: how much side play in throttle shafts is considered
acceptable and when should be rebushed?

Back to screw topic:

Once I found a philips screw without rolled thread in a bag of
computer screws that comes with computer case, it is generic but
there is decent quality brands out there like Antec etc for empty
computer cases with power supply.
