Here’s a challenge. Unusual socket needed.

I’m trying to give an old street lamp a new life.
I need to find and octagon shaped socket that’s is 1-9/16”. Preferably a deep socket.

I’m struggling. Google and eBay are not helping.

I’m unsure if an octagon shapes socket had a special name.

Anyone fancy a challenge that could point me in the right direction? Or even better. Undo the

for me! I’m near Maidstone. Kent. UK.

Try a company called Melform Limited. They are based in Sheffield. They used to manufacture octagon hub nut spanners for early MG's, they may well have a range of sizes.

This place does unbelievable sized sockets in some exotic materials but they also do 8sided ones in various sizes/depths but sadly they are in America and i dread to think what the prices are:

Remember that an octagonal socket is different to an eight-point socket (the latter is not too hard to find, often called a double-square). Is it genuinely an octagon you require? The illustration below (from the excellent Imperial Newton website) illustrates the difference.

Any chance of a photo of the fastener you need to deal with, just in case other "outside the box" solutions can be found?

By my reckoning 1.9/16" AF is a sliver under 40mm.

Deltec and ISS both list octagonal sockets, ISS lists a 1" drive 41mm Budd Octagonal socket at a very modest £23.40. I would have thought that 1.3mm oversize on 40mm would work.

Most octagonal sockets tend to be quite a lot larger since they are intended for hub (wheel bearing) nuts.

Deltec is a bit secretive on sizes but might be worth a call.

Be aware though that unless you can find a relatively common Budd wheelnut socket (like the link above) that will do the job, you are probably looking at well over £100 for a specialised octagonal socket, which may be unappetising!

Have you considered making a traditional box spanner from a length of thick-wall tube?

Thought I had one, but no. It’s 1”13/16 8point deep.

Sorry.

Yep Deltec do them. If they won't let you buy direct, let me know as we carry a large stock of their products and order off them every couple of days usually. I'll have a look on our shelves tomorrow in the "archives" as thats exactly the daft sort of thing we'd have in there.

As an aside Deltec also do specialist socket "hire" so that may work for you if its a one off. North Cumbria Search and Rescue - Team Leader

Thanks for the help.

I do indeed need an octagon shaped socket.

I’ve attached a few photos for you guys to see.

I’d be interested in the hire option if it’s cheep enough. Seems silly to spend money on removing one nut.
At this stage I don’t intend to reuse it again as I want to make it so that any modern human can take it apart should they need to in the future.

Hard to make out exactly how it is configured from the photo. But if it is just a simple eight sided nut and you don't intend to use it again, how about drilling down one side of the nut to put a split in it then it should turn relatively easily with plenty of oil, maybe a bit of heat and a pair of grips. Or even drill down both sides so it splits in two.
