He asked about the "Allen" wrench size for the head of a socket screw, I think.

I had thought the reference was to the nut size, so I deleted my posting. The hex size for a 4-40 size set screw is .050.

Man, I got an IQ over 150 and get more and more confused! LOL!!!!!!!! LL~ LL~ LL~

A 4-40 socket head screw takes a 3/32 hex key.  So I immediately thought of that since the question posed was for a *4-40 screw*.

Now, a 4-40 *SET screw* looks like it takes an .050 hex key....... 

I guess, either way, the question is answered!   n~  n~  n~  n~  :##

yup.

Ok, OK, are we talking about a 4-40 (socket head cap) *SCREW*, or a 4-40 *SET* screw????  Both ARE 4-40! LL~ LL~ LL~ LL~   n~  n~  n~  :##  :X

The 4-40 *screw* takes a 3/32 Allen wrench (also referred to as a hex key/wrench).

Looks like the 4-40 set screw takes a .050 Allen wrench (also referred to as a hex key/wrench).

Well, I have tried to screw up this thread (no pun intended) right from the start. On the outside chance that I missed a way to screw it up, I am going to have one more go at it.

I guess I am weird, but, when I can't find a wrench thats fits I head for my local ACE Hardware Store.  I have learned that if they don't have peice of hardware I need, it isn't to be found.
