Bolt Gauge

[Willy Nilly]

I've been looking for a bolt gauge and found this https://www.ebay.co.uk/p/MMD-Screw-Template-Measur...

There are similar elsewhere for less. Any good, are there any others worth looking at? There's this one, but I'm no sure if it does much metric will be as usefull but it looks like it tells you what size drill to use for various rivets etc https://www.ebay.co.uk/itm/AIRCRAFT-TOOLS-NEW-BOLT...f:0

Over to the panel.

It depends on what variety of bolts you deal with.

I use one like this, the thread gauge can be helpful too, although most of my bolts are the same thread.

Buy a digital vernier for a tenner and measure them yourself.

And a Zeus book or similar.

I use a vernier and a thread file:

Both have multiple uses.
Well, ok the thread file only has two

This.

Pitch options are limited in most applications, and you can count ten and measure that with a very-near as well.

I find it's much easier to use a thread gauge than measure the thread pitch. That and something to measure the diameter is all you need. I can't see the point of the thing you linked to unless you're dealing with a lot of bolts of unknown sizes and need a quick, crude way to classify them.
