Thanks! After decades as a DIYer, I learned something new here; namely, that the fastener length is "whatever goes into the hole". So, for flat-head machine screws, the official way is to measure the *whole* length. Not a big deal if you're taking a sample screw to the store to match, but is important if you're ordering without a screw to match.

It's 5am here and I've been trying to catch up on my drone setup videos when I came across this. Very informative and well-explained! Your effort is much appreciated.

name of the product?

You checked the thread pitch wrong. The ridges are above the labels, but you tested the ones below. For example, at 3:29 you say "I'm going to come over to the 13 and try that", but you use the ridges _below_ the 13. The ridges for 13 thread pitch are actually above the "13" label. At 5:28 you say 18 but are actually on 20.

Yes! Thank you, I have a lot of fasteners I need to measure.

Learning about markings on bolt heads goes a long ways also. If you see three or 6 lines evenly spaced in a radial pattern on the bolt head that's an sae grade 5 or grade 8 respectively. Graded metric bolts will have 5.8, 8.8, 10.9 or 12.9 stamped on the head. On a flathead screw the angle of the countersink is also an indicator. 90 deg is metric and 82 deg is SAE.

Metric nuts have a different diameter, so they will not fit or be loose. They may also have a Metric grade mark, to help initially. I do agree with what you are saying though- anything is possible.

American fastener standards are all written in inch measurements. (IFI, SAE, ASTM, etc). Thread pitch for imperial standards are measured in TPI or threads per inch which come from American standards. These gauges measure USA thread pitches & Metric for non American fastener standards (DIN, JIS, Etc). Most nations have their own standards concerning fastener dimensions.

Paul, you may have skipped over where I explain the nuts. It’s at the end of the video. I mention it in the beginning, but explain it in the end. Thanks for watching. Andy

You don't include the threads portion of the bolt in your length. Only the shank (grip length). The grip length will change with every bolt size. A 6" bolt will have the same amount of threads as a 9" bolt but the 9" bolt will have a longer grip length. The grip length (shank) is the portion of the bolt that is the same thickness of whatever material you are bolting. Bad video.

What are those products which still use standard threaded bolts? Are you repairing very old machinery? Stop perpetuating a stupid system!

Thank you
