[Milsurplus] Connector Assembly/Disassembly Spanner

[KD7JYK DM09]

Auto-parts stores, if you can't find the original.  Look for a "spanner" 
socket, they come in all sizes, from a fraction of an inch for antenna 
nuts to several inches, for axle nuts.

They come in two, three, four, five pin...  I have a small selection 
going back to the mid-80's.

Do a search on google images, for "spanner socket".

Here's a random link to give you some ideas:

Ebay also has a ton of hits, look for spanner nut socket, castle nut 
socket, et cetera.

AND...  They have "inside", and "outside" sockets, for "inverted" nuts...
