To save a bit of fabrication effort I just used a commercial thread gauge. Thread a bolt and its matching nut in each hole...
Attachment 43426
If things get too crowded, use the reverse side of the gauge to stagger the bolt placements...
Attachment 43427
This scheme provides space for fastener sizes you may not yet have in your collection. Also, it accommodates metric as well as inferial fasteners.
Also, having the nuts removable from the board allows checking threads on devices where the stud cannot be removed.
Thanks...I haven't ever seen one of those. I like the idea of removing the nuts!
Mine was a promotional gift from a company with which I do business but they can be had from Amazon...Quote:

Thanks! Next cheapest one of those I've seen was over $20, and I'm too cheap but spend that! ;) And I will make the modifications/additions you suggested!Quote:

That way only the screws that actually fit the threads in the board are screwed into it and the chance of damaging the plastic threads is minimized.Quote:

as well, purchased earlier, but they must be taken off that infernal cable and mounted to a board to make them useful and, when that is done, the result is way bigger and heavier than the little plastic thread gauge.
I have a thread checker in plastic that was under $10, but not really satisfactory. It has samples of the threads protruding from the surface of the checker, too far frm the edges except for the larger screws, and holes with thread OD, but not threaded. Not too useful. Has fastener length gauges for metric and imperial fasteners, too, that are useful, but overall, not very satisfactory. I went through the first 10 pages of thread checkers that came up on Amazon and didn't find anything like it. Got it from the local tool wholesale place, Steve's Wholesale tools for $3 or 4, so out a terrible amount on money on it. I do have a pretty fair collection of metric and imperial hardware, and a 4-84 leaf-type thread checker and similar one for metric threads, so I can identify the correct screws for the upgrade. If I had bought the good stuff 40 years ago, it would have been much better than faking it as I have all these years, but I didn't know then what I know now. And wasn't smart enough to realize it.Quote:

Having to thread each of those nuts off to check for bolts or bolts to check for nuts would be annoying.
Again, I think yours has its place, but I'm always sorting through nuts and bolts. I mean, literally always. At least...that's the way it feels. Being able to grab a bolt and thread a nut real quick helps to sort my confounded nature quickly.
You don't have to remove all the screws/nuts to check an unknown. Measure the unknown diameter and pick the reference screws/nuts that come close to the matching diameter.Quote:

Oh, there may be the occasional confusion (e.g., 8-32 and 8-36), but, having found one of each I lay them out and from then on a visual comparison is all I need.
Nevertheless, each to his own. I wasn't suggesting that my approach should replace yours; merely a variation to be evaluated. In fact, I have several homemade gauges similar to yours but done in all metal.
In planning one's personal approach it helps to see what others have done.
I love a good debate, especially with this type of topic. It's something you can't find on reddit...or anywhere really. People get too defensive. To get down to the nuts and bolts (pardon the pun) and find great solutions, we have to communicate. Your post was an inspiration...it's an idea that I can use to better this board in the future. If I came across as defensive, I didn't mean to be. Thanks for the communication and the inspiration. ;)Quote:

https://www.homemadetools.net/forum/...ize-gage-55329
but if you don't do it often it may be easier to just work it out mathematically. For numbered screws the diameter is computed from...
D = 0.060 + 0.013 * N
where N is the screw number. Solving for N, we have...
N = (D - 0.060) / 0.013
so measure the diameter of your unknown, plug it into the above and solve for N.
If you don't already own thread pitch gauges (inferial and metric), remember that any screw of known pitch can be used as a pitch gauge.
