What is this socket extension for?

[maico]

Called a special 1/2" extension on the Stahlwille website. If you turn it strange things will happen?

That reminds me of a special tool to tighten the bolts for a John Deere two cylinder.

Wonder if the offset suits a crows foot of a particular size bringing the rotation of the ratchet inline(ish) with the flare nut.

I dont know what it's for, but I know if I dont buy one, then I'm going to need it. And I'll figure out what it's for, the hard way.

I see your thinking, but if it did that, wouldn’t it negate the need for a crows foot?

I found more ...

"USEFUL. Stahlwille 12250001 Special Extension, offset, can be used on the Magnetic Switch Diesel Pump to have direct control of the pump."

https://www.amazon.com/Stahlwille-Special-Extension-L-150-d-17/dp/B00GQ5BDEA?tag=atomicindus08-20

Still have no idea how this extension would be used to do that.

I was thinking flare nut on a pipe with an immediate 90* bend, something not uncommon in injector pumps. It'd be similar to a oxygen sensor style socket but more flexible.

no, because it can reach around a corner.

The 1225 above is different than the 3505 the OP is asking about.
His is 1/2 drive not 3/8, has a pin not a ball, and is shorter at 120mm vs 150mm.
While Stahlwille designates a specific use for the 1225, there is no such mention for the 3505.

This is from TengTools 3/8" drive.
Proper tool not modified. Suppose it does serve a purpose.

 

[rpcraft]

Pictured like that and seeing the intended use it paints a better picture but my left sided brain would also ask the question, couldn't you also just use an old school distributor tool?

Never underestimate the ability of a German automaker to overcomplicate even the simplest thing.

Looks like it might come in handy for some crowfeet!

Funny how often that happens
