Concatenate cells and add text

I cant quite get this, I have 4 cells in one row (a selection and can be any row), I need to string the values together and add some simple text.
Example:
Assume row 1 and columns A, B, C, D.

496 | 6d7 | Minor | Ø.375 +/-.010

What I need this to read as one long string:

#496, 6d7, Minor, Ø.375 +/-.010

Adding the text in Red.

Column A may be a single digit or up to 10 digits in length.
Once the string is configured I want to copy it and manually paste in another application. If the string is placed any where else in the worksheet for formatting, it can be deleted after the copy/paste or macro end.

As always, help is appreciated.
