Micrometers are for the ultra-detailed among us. Precision manufacturers, mechanics, and engineers understand, and even the occasional hobby machinist knows the critical nature of accuracy in creating and maintaining the machines we use everyday. Ever wonder why everyone seems to love that outlandishly-priced custom car shop? Maybe it’s due in part to that micrometer they use to discover how uneven those “standard” OEM parts really are. Of course, we all take for granted the extreme tolerances built into Airbus and Boeing’s top machines that sling us around the world thanks in part to an engineer’s micrometer. If “eyeballing it” and using a tape measure aren’t going to get the job done right, consider picking up a micrometer for the very best in precision and accuracy.
