Today I was at the shop I mentioned before and this people are great!

I took one of this rack rails and some original screws with me and they 
sold me the proper tap

for EU 8,07 +VAT (20%).
So Farnell's price is indeed steep.

The sales guy even tried the tap and fixed one of the mauled threads for 
a test.
Very nice!
