G tractors went styled effective 13,000 the beginning of the 1942 production year. Model H tractors were all styled and this screw design was used for all.

And so, with farmers rebelling because they were unable to remove round head screws, Deere (starting with 1950 production) went to Hex Head, Clutch Drive screws. This was the factory fastener for A-B-G tractors through the end of their production runs (1952 for A & B) and 1953 for G tractors. End of Story!
