Hi All,

I think I have a diffuclt request.  I am looking for the nuts  (14pcs)
that suit the  Vishay (formerly International Rectifier) diode set.

Data sheet of diode set
http://www.irf.com/product-info/datasheets/data/203cmq080.pdf

Picture of nuts can be seen here

hex of nut is 8mm total length including head is 14 mm .

Any pointers where I might get them would be appreciated.

How close does it have to be? The data sheet says 1/4-20 thread, you
should be able to get those most any place (in north America, anyway)
with various head styles. A socket-head cap screw with a washer under
it would probably be a good replacement if you can't find a screw that
short.

Those are machine screws, not nuts.  And a glance at the data sheet
reveals that they're 1/4-20 which is an exceedingly common US screw
thread.

Calling them "NUTS" will not get you any and using millimetres wont
help as they are 1/4 inch -20 UNC hex head cap SCREWS.

GOOGLE is your friend. Or  a specialist fastener house in Australia.

** Have you tried a standard 1/4 inch UNC  bolt ?

 Chances are it will work fine.

 Short thread ones are a bit rare - so a hacksaw might be handy ...

 Use SS if nickel plated are hard to find.

Like Phil says short bolts may be hard to find. If its not critical use
a longer bolt & run a nut down the thread.

Plain old gutter bolts sold by most hardwares are 1/4 UNC. Cut the
thread of some & screw them into the diode & then run nuts down the thread.

1/4" whitworth and 1/4"unc are exactly the same. They are
interchangable. 1/2" is the only size where whitworth and unc are not
interchangable (the thread pitch is different).

Short bolts with thread all the way down are available, they are called
set screws and in 1/4" size should be readily available down to 1/2" length.

Most 1/4" hardware is common in zinc plated finish. Stainless steel is
also common.
