Anybody know what these little snap on sockets are for? Part number shows up nowhere, pat. No equally as useless….

Anybody?? I’ve got 3 of them, the drive side is 7/16 or the closest metric equivalent … and the working ends are 5/16 ( small one ), and the other two are 3/8…. Notice 1 is about 3/16 longer than other. The shorter one has thicker walls.

Numbers on side are as follows; (2) 3/8- N7127-6T , and one N 7127-5T (5/16).

I’ve been trying to figure it out for a popular hours with no success, please save me!

Hi. Snap-On made a handful of pass through type ratchets. Some larger for wheel alignments, and others for general use. Yours could be special order with the “N” prefix. They go inside whatever wrench opening they fit, and the ring holds them in place.

Think Astro Nano sockets but with the ring on the socket instead of the ratchet.

So like this? Somewhere I have a snap on ratchet that’s half of one of these… used to have a handle on it from the way it looks… it’s a small ish one… I wonder….

Here is an example of a pass-through ratchet at work.
