This is the Emergency 10mm Socket from the team at SST. It’s the perfect gift for the man who has everything, because no one has a 10mm socket when they need it. That’s just a fact.
Exactly where the “missing 10mm socket” meme started isn’t known, but it was so immediately relatable that it became one of the most common running gags in the automotive corner of the internet. At the end of the day, the 10mm is frequently needed and it’s just small enough to seemingly disappear off into Narnia as soon as it’s accidentally dropped into an engine bay.

Who Invented The Ratcheting Socket Wrench?
It isn’t widely known that the modern ratcheting socket wrench was invented by an American – J.J. Richardson, of Woodstock, Vermont – with its patent approved in June of 1863. It seems that J.J. Richardson’s life is largely lost to history, but one can only hope he reaped the benefits from his invention and lived out his years as a wealthy man.
After all, if it wasn’t for him we’d all be using standard wrenches and everything we tried to get done under the hood would take twice as long. It’s thought the the history of the (non-ratcheting) socket wrench has existed for centuries – they were originally used to wind large clocks and typically had a square head rather than a hex.
The quick release mechanism that essentially all modern ratcheting socket wrenches use was also invented and patented by an American – Peter M. Roberts in 1964.
The Emergency 10mm Socket
