Phillips screws

[Bill Traill]

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! Bill Traill DCO: TC#5221
