Incidentally the size of sockets and screws (including the Allen wrench) is very much a technology. William Sellers pushed standards in the mid 1800s specifically to benefit American industry through interoperability. Standards we still use today.
And the gauges are just as important. Obligatory ref to Brad Cox seminal 1990 paper, Planning the Software Industrial Revolution, and it's compelling analogy with Eli Whitney.
