3/8 Early Sockets

1929 introduction – shows thick set with tapered angles 

Starting in 1927 with smooth socket walls and recessed tops in Catalog F (1929) these sockets seem to remain the same. Shown is a set of these, and they are matched, but 2 have no logos (early manufacture) and the sockets with logos have the underlined Snap-on. This are seen in Catalog F (also 1929), but not in Catalog G (also 1929). The next series are changed to straight walled sockets.

3/8 Second Series 1929 style change

Left is the catalog drawing from 1939 vs the photo

The second series ran from1929 to 1936/7. These have light knurls and a larger logo. The S is enlarged and it is underlined. These were redesigned in 1939. The markings are of various depths and the friction ball holes are not uniform against the logos.

Top is a 1939 set with the logos below 

This series started the chrome plating. It deepened the knurls, and added the rib between the knurl and the smooth area. This rib can be very defined or missing randomly. The finish on these changed during WWII to a zinc or an oil finish. These are darker and very common. Snap on tools were used extensively during the 1942 – 1945 period and flood swap meets and other places even now

3/8 Single Hexagon Sockets

1941 catalog Drawing

Single Hexagon Sockets. The description explains that certain types of nuts and bolts can be under sized and require a single broached socket, because a double broached socket slips. It also explains that Parker-Kalon self taping screws also require this type of socket
