I don’t. Bit excessive for removing a bell box.
I also looked for an 11mm square socket for driving the typical roofing nuts, though in recent times I have got flanged nuts instead (oh-er!) that take a standard 10mm hax socket, etc.
Never found one, mostly square (or bi-square) sockets are massive impact things for the railway industry
These are supplied around me, no spanner or flat head needed

Never seen those in any local wholesalers.
These are the ones we often get:
They have traditional shallow slot head but the serrated flange nuts. They also offer them in hot-dipped galvanised for outdoor stuff:![]()

CEF. I know that’s a swear word on here but my branch is great.
Nice, only the cheap rubbish version available locally, with horrible square 0.5mm thick nuts. I usually use mushroom head hex screws and serrated nuts now.Roofing bolts now have 10mm serrated nuts with a PZ2 head now don’t they? Not seen old school ones for years.
