Eight Point Sockets - What are they for? #tools

In this episode of Socket Obscura, "Dale" tells us about the Great Socket
Conspiracy of 1953, and we look at 8 point, AKA "Double Square" sockets.
These sockets were used for square bolts on old industrial equipment, vintage furniture, furnace fans, garage door springs and semi truck brake adjusters.
In a pinch they can be used as a tap socket. They also work great for pipe and drain plugs.
