Hi,
I've hit a patch where I'm trying to work out thread sizes and types
on a number of objects including hard drive cradle screws in a laptop
and the threaded, pillar  bolt on my router used for fine adjustment.
Can anyone please tell me the best methods that can be used to
simplify the process of measuring and identifying these threads across
the sort of range I've mentioned above?
TIA

Hi Mike,

Get yourself a copy of the "Zeus Tables" -
http://www.tooled-up.com/Product.asp?PID=6505  you will often find this
great little book nestling in the top pocket of a precision engineers
lab coat.  It contains tables that list all kinds of thread types along
with their diameter and threads per inch.

If you can get hold of one, a thread gauge is really handy too.  Metric
& imperial is best.  Doing a search on ebay might throw up a few for a
couple of quid.

Once you can find the diameter of a screw and its threads per inch (
TPI ) for imperial, or thread pitch ( Metric ) you can cross reference
it in your Zeus tablesto determine what type it is.  i.e. Metric Fine,
Metric Coarse, UNC etc...

Alternatively you can probably find various thread size tables on the
web and use a ruler to try and work out thread pitch and diameter.

Thanks ETV, that's a great help. I'll try out all those suggestions
and see what works out best. Much appreciated.
