Phillips screws

Awhile back there was a thread (npi) on the use of Phillips
screws and when they came into automotive use.
The latest issue of Invention and Technology Magazine (Fall
2001) has the story (Author: Curt Wohleber).
Henry F. Phillips of Portland Oregon, was granted a patent
for the screw and driver in 1936. That same year General
Motors used the screw in manufacture of the Cadillac. By
1940 almost all US car makers were using them.
The Phillips design was great for power driving screws thus
cutting assembly time. The bit would pop out when the proper
torque was reached. The author states this "torque-out is
vexing for the casual user". Pain in the ass would be more
appropriate!
It used to be that our best local hardware store, Orchard
Supply had a wonderful selection of slotted screws in steel
and brass, cheese heads, fillister heads, flat heads, oval
heads. Orchard was bought out by Sears & Roebucks about three
years ago and now 98% of the fasteners are Phillips.....$ talks and
service walks!
