what do you all use to take measurements of bolts/holes etc?

I see alot of measurements of various bolts and holes etc on here.

I just wanted to know how you all are taking those measurements when a ruler won't fit in alot of areas.

What kind of tool do I need to buy to take these kinds of measurements?

Say I wanted to check the runout on a flywheel or pressure plate?

What could I use if I wanted to check the flywheel thickness around a bolt hole?

I think that I could save a bit of money and time if I was able to take accurate measurements.

I guess I could get a ruler and then stick an object through the hole and then measure it if I was on a budget, but that won't work for everything.

Any ideas, I am headed over to Harbor Freight soon so I figure now would be a good time to investigate.

Thanks!

I use a didgital caliper for measuring depth, thickness, length and anything else I can get the thing around.

8" Digital Caliper

and I use my tap and die set to measure thread pitches

for thread pitch use this tool. a tap and dye can mess up perfect threads if you guess wrong

Vermont American (VER21938) Metric Screw Pitch Gauge 0.45mm to 2.50mm

Dial indicator for run-out. Depth micrometer for hole depth. Digital calipers (as metioned before) for thickness or width. There are plenty more for more precision measurements but those are the basics.

I would also recommend an outside micrometer. Digital dial calipers work great but the old fashion method works a bit better because it can pinpoint where you are actually measuring.

Just wanted to say thank you for all of this useful information.
