Precision machined parts are essential in modern society, but they are useless if they can't stay in proper alignment and orientation. The components that perform this task are referred to as screw machine products, even though they describe more than just screws.
Pins, bolts, shafts and, of course, screws, are all required to keep the machines and products in our lives functional.
Often relatively small in size, the required volume of screw machine parts is extremely high, making these suppliers a surprisingly powerful part of the domestic manufacturing economy.
