Learn Machine Screw Sizing Conventions

What happens here

The video begins with the father, a Master Electrician, asking his apprentice son about the size of a machine screw shown in his hand. The son correctly identifies it as a 6-32 screw. The father then explains that the '6' in the designation represents the screw's gauge or diameter, while the '32' refers to the number of threads per inch. He reinforces this concept by asking the son to interpret other common machine screw sizes, like 10-24, where '10' is the gauge and '24' are the threads per inch. The father also mentions the existence of 10-28 screws, highlighting the distinction between fine and coarse threads, and notes that fine threads are typically used in electrical applications. He concludes this segment by stating that most cover plates in electrical installations commonly use 6-32 screws.

Goal: Understand the meaning behind machine screw designations (e.g., 6-32).
