DAMAGED BOLT REMOVER 10pcs

Part No. 00-667 (oro2u.com)
Set of rounded bolt/nut removal sockets.
They are a bit odd as they don't have a 3/8 or 1/2" socket hole, they are purely for use inside spanners or sockets.
I've used 1 or 2 of them inside a socket on an airgun, and they did the job, but personally I'd either weld them into

sockets or spanners, and keep them for tight access jobs. Or just hammer them onto the bolt/nut you want to remove, they are cheap so no need to be scared of damaging them.
The smallest socket needs a 16mm (from memory) socket or spanner, the biggest one fits nicely into a 1 1/16"th socket.
