looking for Diode Nuts

Jul 10, 2011 9 Replies

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

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.

My plain old gutter bolts are 1/4' whitworth

Doh! So are mine......

Pehaps some 1/4 unc allthread from bunnings then.

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.
