Hello - all the links for threaded inserts in Europe are Amazon links and the threaded inserts are not cheap. I looked around and found a business in Austria that ships to EU countries. Here is a link to the page with the Hexigonal threaded inserts. I bought from them a few times and they are excellent quality. https://estore-sslserver.eu/ronin.eu They cost from about €7.30 to €10.00 for 100 pieces. Shipping is €9.80 to EU countries ( I live in Belgium and it's what they charge me. ) for what ever quantity you buy. — MA.314A0410 = M4 — MA.645A00506 MZ = M5 these you hammer in — MA-645A006014 Z = M6 these you hammer in — all the others state the "M" size that you choose. I hope this helps someone. The business is honest and you can pay them a number of ways.
