So I’ve assembled a collection of micrometers and vernier calipers of varying quality, and it’s time to dive in and measure some very small things. Some of you will be metrology enthusiasts ...

On the bench where this is being written, there’s a Mitutoyo vernier caliper. It’s the base model with a proper vernier scale, but it’s beautifully made, and it’s enjoyable ...

I'm not sure what size the bolt is, so I'll need to measure it. I've got the vernier caliper as it allows me to take really accurate measurements. I'll then need to get the new bolt and replace it.
