<HTML>My calipers are the dial type and seem to be more accurate than plus or minus 5 thousandths providing they are properly zeroed first. That said, I still make a double check with a micrometer when dealing with wire or pin sizes, just to be sure. Another tool I find useful is a digital micrometer.  Mine is a cheapo Harbor Freight special that was around $20 on sale a year or so ago.  The digital readout is not electronic, but mechanical, similar to a car odometer.  I'm usually wary of cheap tools, but this one has been fool-proof so far.  I sure makes for easy readability.
