Verion Harder case bolts as they are a little bit too soft, but can be replaced easily before the holes get rounded. But

really, they are the same stainless bolts used in all ACS machines and very hard…are u sure there isn’t something else happening, fit of the bit perhaps?

      DavecUK I’m going to have another look when I next do some maintenance with a Bosch hex set a friend got hold of for me. The set I was using is pretty horrible quality so hopefully it’s down to fitting.

        Buy some Wera Hex Plus allen keys, they’re not too expensive but are top quality

          Dusk I’ve heard Wera is god tier. If the Bosch hex bit aren’t great, I’ll upgrade.
