Here's an idea for set-up blocks to use for tablesaw or router table settings:
Go to your industrial supply dealer and purchase a variety of lathe tool bits.
They come in a range from 3/16", 1/4", 5/16", and 1/2". Many are ground to size and
are plenty accurate for woodworking settings. Prefer the ground bits.
(I wouldn't rely on them for calibrating calipers or micrometers though.)
I was also fortunate enough to be able to get a set of precision pin gages (.060 -.250)
by .001" increments, and a small assortment of gage blocks when the manufacturing
plant I worked at closed down. These items have served me well.
But the ground tool bits are invaluable.
Rockler sells brass blocks, but are advertised for an accuracy of +/- .005" this doesn't
sound too accurate to me. A review comment mentioned using them to check the
accuracy af a caliper - I don't recommend using them for that degree of accuracy.

You need to move this to shop tips...
It's a good one...
But I have a question...
.005" = 1/200th's of an inch...
Working that tight with wood consistently is nearly impossible...
Just working at 1/64" with regularity is an IRL achievement..
