7mm square socket?
« on: August 19, 2019, 12:55:22 PM »
After spending several hours trawling the internet, with not much to show for it, I am still searching for a 7mm square socket to fit a 1/4" drive ratchet. A 5mm square would be handy too.
Is this looking for the impossible? Or does anyone know better?
Thanks in advance.
Pete

Pete can you use a larger hex socket and some nuts, cut the nuts in half and cut/mill each half for a square section.  You need two nuts for each half as you will cut each one over centre.
Just get doing and make swarf, you can decide what its going to be later.   :thumbup:

Joules, thanks for the suggestion. That is one way round the problem. :thumbup:
I was trying to save on unnecessary work though.
It seems that I may have to make my own socket, (having no wish to try and re-invent the wheel), if such a thing is not available.
Guess there are not many square nuts about!

Send me a bit of copper milled 7 mm square a couple of inches long, with one end turned circular so that I can grab it in a collet, and I'll pop a 7 mm square hole (*) in a bit of bar end that you can weld onto a scrap socket.

(* using my Diesinker EDM machine)

Later Edit: Or also send me a 6 mm square copper bar and I'll pop 7 mm in one and and 6 mm in the other thus making a socket. It would help alignment and flushing if both bars had an axial hole of (say) 3 mm or so.

Laser 6058 tap holding sockets? Or an adjustable tapping chuck? I suppose it depends on what you are trying to do.
