I bought this 1/4" what I thought was a finger wrench the other day and it ends up its not. I tried looking it up but the initials (SW) dont seem to be any major manufactures, that I know of anyway.

So both sides are 1/4" drive. The male 1/4" drive side is attached to the main body. But the inside one (that goes onto the ratchet) can move. You can grab the knurled ring and it acts like ratcheting screwdriver. In the middle it wont move in either direction. If clicked to the left or right it will move in either direction. As I was pondering it more, Im thinking maybe some sort of torque limiting adapter. There is not adjustment, so I don't know. Any thoughts???:confused:

I think the SW stands for stevens walden company. It does look like a ratcheting torque limiter. What does it say S4FT? :headscrat

Just to add, SW 3150 is a 1/4" ratchet, so I'm willing to bet SW 03155 is a 1/4" ratcheting adapter.

I'm just thinking (or probably not thinking) out loud here ..... but a 1/4" breaker bar? I don't think I've ever seen one of those so I was surprised that this SW 1/4-1/4 thingy would be used on one. It doesn't seem like something that you'd use a 1/4 drive on would be torqued tight enough to warrant a breaker bar and, if so, the force to break it lose would snap the bolt. But what do I know? Sorry for the stupidity.

1/4" breaker bars certainly exist, and that SW thing really is a ratcheting adapter...

Back-in-the-day basic socket sets were often sold with just a breaker bar as the drive tool. It's sometimes difficult to remember that when a ratchet is simply taken for granted today, but the adapter allowed the user to save up a few more dollars to buy an item that would greatly increase the utility of his set.

Hey watch what you saw about 1/4" breaker bars, I thoroughly enjoy mine. Get one that is round and knurled that way you can spin it between your fingers. 90° to break and tighten, 180° to quickly spin the fastener.

No offense meant. It just seems strange to think of the ratcheting mech being part of each socket rather than on the head of the drive mech (now called a ratchet).

The ratcheting adapter goes between each socket and the breaker bar. Just think of it like the ratchet was two separate pieces.

¼ breaker bar comes in handy sometimes. They don't have the height of a ratchet, so with a socket on it, it will fit in tighter places, sometimes places where nothing else fits.
